CORSAIR – NIGHTSWORD v2 WIRELESS SD Stream Deck Gaming Mouse – Wireless – Black

Fantastic doe bigger hands - I ca.e from a Kone xp air which I loved. I still have it but its clicks are mushy and it seems to be a bit buggy with polling rate and can feel just weird. I waited for this one to come out as it is a bigger mouse, lighter than the kone, updated software and hardware, and the elgato button. I havnt fully explored the 1 button for everything in gaming yet as when i used it, it woukd cause a hitch like it was a seperate window opening up. This is minor as I only lost 1 buttong coming from the kone and its got web based software. I would like to see this worked on if possible as it is marketed that way and you can have hitching in games.

Surprisingly great for productivity - I love my Stream Deck, and so I was interested in the idea of a mouse with dedicated functions. As a mouse, the Nightsword v2 is excellent. It has fantastic tracking and response time through the wireless dongle and it's comfortable in the hand. Button placement feels natural and it's generally ergonomic overall. Build quality feels solid though it's a little lighter than I'd like. I'd have appreciated the ability to add weights, like some of my other Corsair mice. The LED lighting is nice without being overstated. I enjoy the fact that it can be controlled through Corsair Web Hub. iCue is... fine, but it's often glitchy and I'd rather not have to run it, so this is great. I know this is a gaming mouse, and I'm looking forward to fully taking advantage of some of it's features when I have some time to sit down and really put some time on it, but I've been primarily using it with Blender and I'm loving the software integration. It's very customizable, and being able to quickly hit some of my more complicated functions onscreen almost immediately is a treat. There's a huge library of plugins, tools, hotkeys and such available to customize to your liking. Overall, I think this mouse is a great choice for any sort of task you want to take on, and I'd absolutely recommend it.

Really like the Streamdeck features of this one - This mouse works well for both gaming and office work, and that flexibility is what I appreciate most. The Stream Deck features help with things I actually do. When I’m gaming, I use the voice chat controls. Having them on the mouse makes it easier to handle the conversation while staying focused on the game. It’s a small convenience, but one I notice all the time to make my play time move fast. The same idea carries over to work. During calls, it’s much easier to come off and on mute, and I can use the Stream Deck controls to share my screen. Those are ordinary parts of a meeting, but they’re also moments when I want a control to be quick and easy to reach. I like that the mouse is useful after the game is over, too. The extra controls have a purpose in both parts of my day. The only thing I would change is the weight. It’s a bit lightweight for my taste, and I prefer a mouse with a more substantial feel in my hand. That’s a personal preference rather than a deal breaker. The Stream Deck controls make voice chat and work calls more convenient for me, and it’s a great mouse overall.

Excellent High Spec Mouse... Software not so much. - The Corsair Nightsword V2 Wireless SD is the perfect ergonomic mouse built for streaming, gaming, and productivity. It has 11 remappable buttons with optical switches rated at over 100 million clicks, 8k polling, and the 33k DPI iCUE Marksman S sensor, so your inputs are precise no matter what you use it for. It boasts tri-mode connectivity for the most adaptable setup covering you on the go or in hardcore gamer mode. Use Bluetooth on one PC for productivity tasks or mobile work setups, move to a wired USB setup if you game in high-performance setups, or use the included USB dongle for fast, zero-lag wireless gameplay comparable to a wire. For me, this is the most comfortable gaming/work mouse from Corsair I've used to date. It fills out the palm and fingers land in natural shape and you can easily find buttons without looking. I love the included USB C to USB A dongle dock that has a solid metal clip to attach to your mouse mat/pad or clip to your bookbag pocket so you don't have to search when needed. Overall, this is an excellent mouse for my gaming and productivity needs. I would have liked to see the inclusion of grip stickers for a more customized feel, but the finishes and textures are good enough. Battery life is excellent, rated up to 170 hours depending on RGB usage and polling speed. This is plenty for me, and it has a built-in rechargeable battery so you never have to search for AA's again! I get through a whole week of regular productivity/work and an entire weekend of long gaming sessions (like 5 hours for 2 days) with RGB on. If you turn off RGB I am sure you will get even longer! No gripes here, you get more than enough playing time on a single charge. Love + Tri-Mode with rechargable battery (USB, Wireless 2.4GHz, and Bluetooth) + Love the thumb rest and ergonomic shape. Wish there was a pinky rest too and it would be perfect. + The grip and finish feels nice but if you get clammy or sweat while gaming, it can become slippery. + Love the plethora of buttons that are all mappable. I simply use the SD button as another modifier like the CRTL button to make selecting multiple files without touching the keyboard when in "work" mode. Make it a sniper button to drop DPI in gaming. Could Use Some Work -Software has no way to configure via Bluetooth. It is ONLY accessible via web browser and not compatible with iCUE. -Only recognized via USB for configuration. Lose the dongle, USB cable is the only way to connect and configure. -No infinite scroll. Would love to see this added to balance the weight distribution. It's a great mouse, but the software feels beta. To activate your streaming functionality, just download the StreamDeck software and select the Nightsword to get more macros but doing so makes the mouse quite confusing. I found it is better to not use the StreamDeck fuctionality since I have a stream deck. The mouse introduces a mouse menu which creates a virtual streamdeck that becomes an annoyance for me. If you stream, you must likely have a stream deck so this is basically an extra button. Software is clunky and doesn't seem ready for primetime in my opinion. It is an excellent high spec mouse with many buttons, but if you own a streamdeck already, I found myself just skipping the SD button all together.

Really good and Stream Deck integration - Overall – I really like this gaming mouse. It is comfortable to use, has plenty of buttons, and gives me a lot of options to customize. I really like the Stream Deck integration once I got everything working. The problem was getting it working in the first place. The instructions that came with the mouse are basically nonexistent (see the QR code note below). When I found the manual online, the Stream Deck integration instructions did not work. I ended up having to do some searching online to figure it out. Once I finally got it working, though, it has been very easy to use. Touch and feel - The mouse feels good in my hand, and I really like the thumb rest. It makes the mouse comfortable to use for longer periods of time. The buttons have a good feel, and there are enough of them to give me plenty of options without feeling like I'm trying to figure out where everything is. Setup– Connecting the mouse was easy. I was able to connect it through Bluetooth or USB without any problems. The Stream Deck setup was a different story. The instructions provided did not work for me, and I spent some time searching the web trying to figure out what I was missing. Once I found the right information, getting it set up was pretty easy. Functionality– There is a lot you can customize on this mouse. I can change the lighting, DPI, button assignments, and create macros. This is a great feature, and you can tune it for certain gameplay or make any adjustments for your system. The Stream Deck integration is probably one of the best features. Once I got it working, I was able to map the mouse buttons to Stream Deck actions. Gives you options without having to reach for another device. You have the option to use Bluetooth, wireless, or plug it in with USB. I had no problem with any of those connections. The scroll wheel works fine, but I do wish it had an infinite scroll option. One other complaint is the QR code for the manual. Instead of taking me directly to the manual, it takes me to the product page. Not a showstopper, but when I was trying to find instructions, it would have been nice to not have to stop and search. Bottom line– It is a comfortable mouse with a lot of customization and some really useful Stream Deck features. The biggest problem for me was getting the Stream Deck integration set up, and I had to search online for help. Once I got it working, it was easy to use. The comfortable thumb rest, multiple connection options, macros, and customizable buttons and there is a lot to like here that offset the manual issues.

Wireless mouse with extras! - I’ve been using the Nightsword v2 Wireless and I’m really liking it so far. I wanted to get away from having another cable running across my desk, but I also didn’t want to give up the extra buttons and customization I’ve gotten used to with a gaming mouse. This ended up being a really good fit. The mouse feels great in my hand. I actually prefer a mouse that has a little substance to it instead of something that feels almost weightless, and at 89 grams this feels like a nice middle ground. The right-handed shape and thumb rest are comfortable, and overall it feels solid and well built. Wireless performance has also been great. I haven’t noticed any lag using the 2.4GHz connection, and you also have Bluetooth and USB-C wired options. The sensor goes up to 33,000 DPI and supports up to 8,000Hz polling. I’m not going to pretend I can tell the difference between every polling rate, but I can say that it feels extremely smooth and responsive when I’m actually using it. The feature I find most interesting is the dedicated Stream Deck launch button. One press brings up the Virtual Stream Deck, and from there you can basically build your own Stream Deck on screen. You can set up different actions and shortcuts depending on what you actually use instead of being stuck with a preset layout. There are also 8 programmable buttons on the mouse, and the Elgato Marketplace opens up a ton of additional plugins, profiles and other options for customizing your setup. That’s probably what surprised me most about this mouse. The Stream Deck integration isn’t just something for streaming. I’m finding plenty of things I can use it for during normal computer use too. Once you start setting up your own shortcuts, there are a lot of possibilities. Corsair also lets you customize things like DPI, button assignments and macros through its web hub. I like being able to make changes without installing another full piece of software just to adjust my mouse. If I had to find something to complain about, this probably isn’t for someone looking for the absolute lightest gaming mouse possible. There are definitely lighter options. Personally, I like the weight and the way it feels in my hand, so that’s not really a negative for me. Overall, I’m very happy with it. It’s comfortable, responsive, has plenty of customization, and the dedicated stream deck button and ability to build your own virtual stream deck make it different from most of the other gaming mice I’ve used. I originally looked at it as a wireless gaming mouse, but I’m actually getting just as much use out of the extra controls for everyday computer use. Definitely recommend for users who like customization.

The Nightsword Has It All! - The Corsair -NightSword v2 Wireless SD Stream Deck Wireless Gaming Mouse offers a level of customization only seen on more expensive gaming mice. I am impressed by the build quality of this Corsair it seems very well made, with a nice fit and finish while being lightweight at the same time. The extra buttons are very well thought out and shaped in a way to make them easily usable and distinguishable from the other buttons on the side. Not only that, I like the responsiveness and robust feel they have to them. The Stream Deck integration is a nice add-on as well and the Corsair web hub makes it easy to assign the buttons to whatever task you like, along with being able to change the lighting on your mouse. I have had other wireless gaming Mice before and I can tell you this is my favorite one already in the short time I have had it. It just feels better than the other ones I have had and it looks good too. I do still wish they would make a larger version, though, for my big hands. However, I have been quickly adapting to the feel of the NightSword, which surprised me because I do not remember a mouse feeling better the more I used it before this one. If you thought that wasn’t enough, there is a system called Elgato that lets you do even more customization when paired with a Corsair Stream Deck. If you have not gotten into Stream Deck yet, you really should if you spend a lot of time working on computers. I have always liked Corsair products and I appreciate their continued innovation, especially when it simplifies things. The Corsair-NightSword is a very responsive gaming mouse when used wirelessly with the included USB Wi-Fi dongle, but it also has Bluetooth for versatility and it comes with a long USB-C cable if you want to use it as a wired mouse. I really think Corsair hit a home run with this one. If I were a person in search of a gaming mouse that can double as a workhorse with unmatched versatility, the NightSword is a top choice for sure!

Feature rich, great for gaming and everything else - This Corsair Nightsword V2 Wireless Stream Deck gaming mouse is a fantastically engineered gaming mouse. It combines a perfect blend of comfort, function, and practical modern workflow features with easily customizable macros, shortcuts, and multi‑actions. It has a craftily sculpted, full‑bodied, right‑handed grip that fits perfectly for palm‑grip users. This mouse maintains a sturdy and stable feel during long gaming or work sessions with minimal hand/wrist fatigue due to its large, full-body design. Build quality is solid and feels like it will be durable enough to sustain years of intense use and pounding. It's very lightweight, coming in at 89 grams, which I guess is still considered a bit heavy to the hardcore gaming world, but I find it feels like almost nothing in my hand and glides effortlessly for a long as I use it. I also like a little bit of resistance feedback so this doesn't bother me. The optical switches deliver crisp clicks and a premium feel with nice tactical feedback during use as well, which I appreciate. Switches area also good for an estimated 100 million clicks, so should last a while even under the heaviest use any person could ever throw at it. Performance stands out for the mouse with its 100-33K Marksman S sensor which offers exceptional precision, tracking, and smooth response across a wide range of DPI settings. The Marksman S sensor combined with an 8000 Hz polling rate deliver responsiveness that sets the mark for top-tier esports mice. weight places it outside the ultralight category, but again, I actually prefer to feel it in my hand. Connectivity options add flexibility in this mouse with tri‑mode options, letting me switch between Slipstream wireless, Bluetooth, and wired operations depending on my setup preference, but all work flawlessly and are simple to setup. Battery life is another highlight, stretching up to 170 hours on Bluetooth and well over 100 hours on 2.4 GHz. This makes it an easy choice for marathon gaming or work sessions - or if you're like me and don't want to worry about charging it but once a week. The most notable and obvious extra defining feature of this Nightsword V2 Wireless mouse is, of course, the Stream Deck integration. This is a dedicated side button that quickly opens a fully customizable radial menu powered by Elgato’s Stream Deck ecosystem. This allows instant access to macros, shortcuts, and programmable multi‑actions without the need for an entirely separate Stream Deck device. For me, this has been a super-handy while gaming, but it's also a valuable feature for gamers, streamers, and anyone who relies on complex workflows where the programmable macros can but put to use. Whether I'm triggering OBS scenes, activating ability chains, or launching productivity shortcuts, the integration is simple and instant, really setting this mouse apart from the traditional gaming functions found in others. Overall, this Corsair Nightsword V2 Wireless SD mouse has been fun to use and proven itself as a powerful and versatile mouse, combining 2 peripherals into one really. It has really improved my flow both gaming, working, or generally screwing around. It's essentially a full-blown command center at my fingertips and has been fun getting used to.

Bringing more use out of a everyday device - It is really nice to see something like a dedicated El Gato Stream Deck Software incorporated into a device that is used every single day. I am all for devices simplifying our everyday lives. The coolest thing is that the button itself is very customizable. Overall feel, it has a great grip and comfortable as a productivity oriented device. I wouldn't say that this is gaming oriented but it works well for gaming, given you are a little cramped on the left index button due to the extra buttons a top on the left. El Gato stream deck software is easy enough to use. You have full customization features to add any commands to your mouse buttons. So, while technically you do not have to do stream deck specific customization, you can still utilize the multiple buttons to program whatever you would like to launch. Much of the settings can be found on the Corsair Web Hub link. I think that you can have a really good thing if you setup the button as a virtual stream deck though. There really isn't too much information to go off of building effective profiles. I would recommend that you still have a dedicated stream deck to further enhance your productivity. Being able to save your stream deck profiles to the Nightsword v2 is a huge plus as well. Meaning you can take your device from home to your office and all your functionality follows along. I like where things are going with this inclusion. I do think some research is needed in regards to making it easy for the everyday user to build up their profiles and be able to customize based on expanded functions within programs or streaming. It's difficult to compile data because it is technically a Corsair hardware/device but a single button controlled by El Gato stream deck is what controls their own functionality.

Stream Deck Keys Are Pretty Useful - Contents Contents include the mouse, a USB-A to USB-C cable, a USB-A to USB-C adapter, and wireless dongle. If you want to see the user manual, there is a QR Code on the inside of the box. It doesn’t take you directly to the product, so you’ll have to search for the Nightsword mouse. Setting It Up I recommend starting with charging the mouse. If using the wired setup, the setup is mostly plug and play. If using the Slipstream dongle or Bluetooth you’ll be paring the device. You can use the wire and USB adapter to bring the Slipstream dongle closer to the mouse for more accurate control. Once connected, you go to the Corsair Web Hub (website) and check for a firmware update. It will tell you that you have to turn off any previously installed iCue software while using the Corsair Web Hub. The Web Hub will allow you to set up buttons, DPI speeds, and lighting effects. Note that you cannot use the iCue software with this, but if you want to control it offline there is a downloadable app for the Corsair Web Hub. Then you will need to download the Stream Deck App so that you can use your Stream Deck features. Apps and profiles can be download from the Elgato website connected through the Stream Deck App. The Elgato apps are installed through drag & drop within the Stream Deck App. Appearance and Feel I have large hands and I think that the mouse is a good size. I have several Corsair mice, and this one is one of the lighter weight models. It doesn’t feel as premium to me, but I think that it’s just because of how light the mouse is. RGB is limited to the scroll wheel, the Corsair logo, and just under the logo. It may take a little getting used to the mouse without accidentally hitting buttons. There are several added buttons that most mice do not have, especially at the thumb side. Stream Deck Keys I tend to use the Stream Deck keys for productivity – my favorite is controlling my music. I could see that it would be useful for streamers and gamers. The key seems to be finding the right SD profiles and apps through Elgato. I’ve had frustrations finding the functionality that I want and getting it set up on the devices. One of the buttons takes you directly to the Elgato page. This is a button that I have a harder time not accidentally pressing. I was curious how the mouse would work with another Stream Deck key device. I already have the Galleon 100 SD keyboard, and wasn’t sure if this would conflict with the controls on the keyboard. It seems to actually work really well. I haven’t noticed any issues with using multiple SD products. Mouse Functions You can make multiple profiles for the mouse if you want different settings or RGB styles. Also, you can assign a button to toggle through the different profiles. The settings provide great control over DPI. The speed can be set for incredibly fast movement – up to 33,000. It has 8000 Hz hyper-polling through wired and Slipstream wireless. The RGB lights can be set for aesthetics with color movement and changing color values. They are also used as indicators for things like DPI stage and battery status. The mouse can be connected by Bluetooth, wireless, and wired connections. Bluetooth is more for convenience. Wireless and wired connections support the best speeds. Battery life depends on connection, RGB settings, and DPI stage. Conclusion I’m giving the Nightsword V2 Wireless mouse a 4 star rating. I think that it’s somewhere between 4 and 5 really. It feels good in hand and there’s a lot of control. The Stream Deck keys are useful, but they aren’t easy to set up unless you’ve done it before and you have your apps selected. Overall, I think this product has a wide appeal, especially to those who like to customize settings.

Everything's a Stream Deck Now - Ever since Corsair acquired the company that makes the Stream Deck they've been slowly incorporating it into more and more peripherals. Every time they do it, I think they've done it, and there's no way they can put it into anything else. Now I guess I'm just going to wait for the Stream Deck earphones to come out. As a gaming mouse, the Nightsword is quite good. It's reasonably lightweight but still more comfortable than most of the e-sports focused gear on the market, and offers a true abundance of programmable buttons. Some take a little getting used to, particularly the two side mounted ones at the top, but once you adapt it's honestly a little hard to go back. RGB effects are present but somewhat understated, and battery life is quite good. The party trick, of course, is the built in Stream Deck. When I first heard of this feature I imagined one of those MMO focused mice that has an entire numeric keypad slapped on the side, but Corsair has gone with something a little more understated and, IMO, usable. Using the button will bring up a virtual keypad on the screen which you can set up to run a variety of commands and macros with the flick of the wrist, then dismiss once you're done with it. It is better and worse than the traditional approach. Better in that you don't have to take your focus off the screen or pull your hands away from the controls. Worse in that it does effectively disable your mouse for a few seconds, and is harder to operate from pure muscle memory. From the perspective of someone trying to run a stream I think this probably wouldn't be the preferred option - but for someone looking to set up macros for productivity or to get an edge in games it might actually be a little better. Either way, I don't think you'd be going wrong trying this very solid mouse out for yourself.

Comfortable mouse with a few problems - Overall, I really like the Nightsword v2 as a mouse. It’s exceptionally comfortable, lightweight, feels very well built, and after about a week of using it for 8 to 12 hours a day, I would probably put it among some of most comfortable mice I’ve owned. Unfortunately, I have two pretty significant pain points that keep me from loving it as much as I otherwise would, and one of them has actually made me question whether I’ll continue using it long term. My biggest issue is the placement of the DPI up and down buttons. They almost form a rocker that hugs the side of the left mouse button, and for whatever reason I cannot stop accidentally hitting them. I’m talking 10+ times a day. Since I work from home and use my mouse all day long, I’m accidentally changing my DPI at least once, and it has been driving me crazy. You can reprogram the buttons using Corsair Web Hub, but that doesn’t really solve my problem because then I’m just accidentally firing off a different command. I could disable the buttons entirely, but I live in the “more buttons the merrier” camp, so I hate giving up two perfectly good buttons. Corsair Web Hub itself is browser based, so you don’t need to install the iCUE software. The web hub is basic and fairly easy to use, but It feels a little empty at times. My second issue has been Stream Deck integration, and unfortunately this one has been a nightmare on my primary desktop. The dedicated Elgato button is supposed to bring up Virtual Stream Deck, giving you an on-screen panel of shortcuts, apps, macros and other actions. I have never successfully gotten that feature working on my desktop. I spent several hours over multiple days troubleshooting it. I updated the mouse firmware and drivers, reinstalled the relevant software, killed every potential conflicting program that could be controlling the mouse or its lighting. When I look at my logs. Stream Deck could actually see the mouse, but its logs showed the device being rejected because it was unable to establish Corsair’s Bragi protocol. Basically the handshake wouldn’t initiate, leaving the mouse undetected through the Stream Deck UI. I consider myself pretty technically proficient when it comes to software troubleshooting, and I still couldn’t get past it after many many hours of troubleshooting. I eventually pulled out my laptop as a last-ditch effort and was able to get the nightsword recognized, which at least confirmed that the mouse itself wasn’t defective. Once connected, Stream Deck actions appeared as options for the programmable mouse buttons. However, I found the setup less intuitive than I expected. The dedicated Elgato button initially just opened an Elgato webpage rather than bringing up the Virtual Stream Deck panel I was expecting, and I had to spend more time figuring out how everything was supposed to be configured. Battery life, on the other hand, has been fantastic. I didn’t even fully charge the mouse when I took it out of the box, and I still got almost an entire week of heavy use before needing to recharge it. That’s with me using a mouse somewhere around 8 to 12 hours a day, pretty much every day. The mouse also supports polling rates all the way up to 8,000Hz. I’ve since increased mine from 1,000Hz to 4,000Hz, and the mouse feels exceptionally smooth and responsive. If I view this as just a mouse, then I love it. The shape is extremely comfortable, it’s lightweight without feeling cheap, tracking has been excellent, battery life is great, and replacing my worn-out previous mouse with this initially felt like a no-brainer. But after living with it, I’m effectively losing three of the buttons that helped make the nightsword appealing in the first place. I can’t stop accidentally hitting the two DPI buttons, and I still can’t get the dedicated Stream Deck button working properly on the desktop where I actually use the mouse. I suspect some of the Stream Deck issues will eventually be cleaned up through firmware and software updates, especially since this is such a new product. The hardware itself is excellent. Right now, though, the button placement, poor instructions snd frustrating Stream Deck setup really stop the nightsword from living up to its full potential.

Not comfortable for large hands - This mouse has a few things going for it, but I'm having trouble getting past the other stuff. What works: --------------- The mouse is has plenty of programmable buttons, but not too many. Configuration of the mouse is via the Corsair Web Hub, which is very lightweight, yet still very functional. I've been using the Elgato Stream Deck ecosystem for a long while and having access to those functions from this mouse are fantastic. It's yet another area of configurable functionality that works very well. Lighting effects of the mouse are also cool, simple, and not overly done. What doesn't work: ----------------------- I would think the shape of the mouse would make it more ergonomic, but that hasn't been my experience. I have larger hands and this mouse doesn't have a pronounced enough arch to feel comfortable. The buttons, being plentiful, are also a bit oddly placed. The programmable buttons are a bit awkward to press. Ironically, the Elgato button, which is normally used to activate the Stream Deck software, is far too easy to press. It's the most accessible extra button, but it's so accessible (and sensitive) that I'm constantly pressing it accidentally. It's really getting in the way of my workflow. Overall, the mouse is also a bit too light for my tastes, making it not feel as...substantial...in my hands. Perhaps that a personal preference. But at the end of the day, I don't find it particularly comfortable to use for my larger hands.

Interesting Stream Deck Integration in a Mouse - The Nightsword v2 features integrated Elgato Stream Deck integration, but is this actually a mouse feature or just a software feature that's locked to this specific SD branded mouse? Other than the side button, I don't really see how its not just a software integration with a Virtual Stream Deck overlay and assignable Elgato keys that bind to your mouse. That said, the Stream Deck integration is actually really quite useful, not so much for gaming but for productivity and general usage. The number of integrations that Corsair/Elgato have managed to integrate is extremely impressive to the point you can really control your whole home from your desktop PC. With this mouse, you can additionally command a bunch more shortcuts with the press of a button by binding the Virtual overlay to the side Elgato button (or any other button) and then get access to more shortcuts. For my needs, this is actually super handy for work because I am constantly on calls and there are some keys I use frequently, like talk, mute, share screen. I also frequently use some programs like Snipping Tool to mark up and cut out screenshots for documentation so that is a real time saver for me to just pop that up with a virtual overlay. One thing I would like to see is the ability to pop up the overlay right at your mouse cursor to save you the travel of going back to where you last moved the overlay. I took off a star because the mouse itself is really not that nice. No infinite scroll wheel, heavy, plastic that doesn't feel premium, kind of light and slick vs. some of the rubberized ones I own. The thumb landing is also really sharp and flat and while the buttons feel ok, they're not as nice as the ones on my other recent mice. It does have left/right tilt on the scroll wheel which is not a given with Corsair mice so that is a nice touch. I also like BT in addition to slipstream 2.4ghz RF dongle which is also another Corsair hallmark, although the BT does feel a lot lower poll rate and jerkier compared to RF. The other reason I took a star off is that there is TOO MUCH weirdness to setting up Corsair mice. There's the dongle firmware update utility web page. The mouse web-hub page and then there's iCue which can't co-exist with the web-hub page. And, if you somehow manage to disconnect the dongle like I did in iCue, you need to re-pair the mouse via the dongle firmware update page bc iCue only gives you keyboard press combos. Its all very frustrating and ofc no one includes manuals or even quick start guides anymore physically so you have to go digging online for it. Pretty miserable experience of tons of firmware updates and then when I finally got everything updated, I still had to re-launch Stream Deck multiple times and then launch it as admin (as it stated in the quick start guide that wasn't included, only online), I finally got Stream Deck to show up. Bad integration, bad user experience, cool Stream deck integration, just an OK mouse. But I really do like that Stream Deck integration and the ability to go RF and BT will come in handy swapping between my work laptop and personal desktop.

Really ergonomic and easy to use gaming mouse! - This is a really great gaming mouse. Corsair has outdone themselves with this mouse - it feels lightweight but heavy duty at the same time. It's also really comfortable to use for long gaming sessions. Initial setup is also really easy - it supports wired, USB Radio Frequency (with the included adapter), and Bluetooth connectivity. All three are really easy to setup with a Windows PC. The default settings on the mouse also ensure a smooth mouse movement experience and it has really fast response time on all three connection types. There is no noticeable lag on RF or Bluetooth connection either, making for a great gaming experience. It also has a built-in Elgato Virtual Stream Deck button which works flawlessly. There are also 8 buttons on the mouse that are fully mappable with the Virtual Stream Deck. That was super easy to setup too. It also advertises 170 hours of battery life and while I haven't used it for nearly that many hours yet, so far it has lasted through several long gaming sessions without prompting me to recharge it. Overall, the Nightsword v2 mouse is a high quality product that works great!

Your Next Gaming Mouse (or Productivity Upgrade!) - Corsair has made some truly excellent products over the years, but the Nightsword V2 takes the cake in terms of ease of use for customizability. I love having extra buttons ready to roll with minimal effort (and surprisingly no bloatware!) and the ability to launch the Stream Deck with one click is pretty savvy. For a chill extended gaming session, the fewer unnecessary clicks that take you out of the game, the better. It’s not the flashiest of all gaming mice and fully kitted out with LEDs and all that - but the design niceties mean you aren’t sacrificing cool design for functionality or vice versa. The base of the Nightsword has that extra little swoop which gives the whole mouse a more stable feel while also maintaining a very light weight for the whole device. You’ll have to adapt slightly to the placement of the thumb buttons but I found that after about 15 minutes most of my muscle memory from my previous mouse was sorted out. The ergonomics for right-handed users seem to be really well-thought-out and the mouse was comfortable to use and all the buttons are comfortable to reach. The responsiveness of the device and multitude of pairing options mean that you can sort out whichever connectivity modality works best for your setup… and worth noting that I couldn’t find a configuration that resulted in any sort of measurable latency. I tried it out on a few games and then let my kiddo try it out on a few of his, now we’re fighting over who gets to keep it. Even if you’re not a gamer, if you’re a graphic designer or someone who needs high-responsiveness with your mouse, if you need a device that has a few extra buttons to swap tools quickly, or even could utilize the extra features of the Stream Deck, this is a great upgrade for you.

A Mac Productivity Game Changer - The Corsair Nightsword v2 Wireless SD is one of the most unique peripherals I’ve put on my desk in a long time. Pairing standard gaming hardware with Elgato’s ecosystem sounds gimmicky on paper, but after testing it out daily on a MacBook Pro (M3 Pro), it has completely changed my daily workflow. The Virtual Stream Deck Experience The built-in Virtual Stream Deck functionality is easily the standout feature—honestly, it might be the single best productivity add-on I’ve used on macOS. ⚬ Endless Flexibility: The sheer amount of customization is wild. Diving into the Elgato ecosystem gives you access to a massive library of plugins, hotkeys, smart profiles, and custom icon packs. It can feel a bit overwhelming at first glance, but in the best way possible once you tailor it to your setup. ⚬ Mac Workflow: Being able to trigger multi-action shortcuts, app launches, or media controls directly without needing a separate physical deck taking up desk space is a huge win. Software & Setup ⚬ Corsair Web Hub: Managing the mouse settings through Corsair's browser-based Web Hub is a breath of fresh air. It works seamlessly and means one less bulky software suite you have to keep permanently installed on your local drive. ⚬ The Software Hiccups: It isn't completely bug-free on Mac. Occasionally after waking the MacBook up or logging back into a fresh session, the Elgato connection will freeze or fail to register. Fortunately, a quick force quit and restart of the Elgato app fixes it right away, but it’s still an occasional quirk worth keeping in mind. The Hardware & In-Hand Feel ⚬ Ergonomics & Sensor: The body fits naturally for palm and claw grips with solid thumb support, and the wireless tracking is snappy with zero perceptible lag during daily use or fast gaming sessions. ⚬ Tactile Inputs: The dedicated extra buttons are well-placed, giving you instant physical access to your virtual macros without accidental clicks. The Takeaway If you want an ergonomic wireless mouse that pulls double duty for serious productivity shortcuts and gaming, the Nightsword v2 SD hits a sweet spot. Despite the occasional minor software restart on macOS, the level of customization and the convenience of the Virtual Stream Deck make it an easy daily driver recommendation.

Features that maybe aren't for everyone - In gaming or everyday use, I always prefer ergonomic mice. As I’ve gotten older, I’ve started having issues with carpal tunnel and an ergonomic mouse makes a huge difference for me. With that in mind, the NIGHTSWORD v2 WIRELESS felt comfortable almost immediately. The shape fits my hand well. I didn’t feel like I had to find the right way to hold it, which I think is the case for some ergonomic mice. Sensor is fast and accurate and no issues wireless. It feels like a premium mouse with excellent build quality. The Stream Deck integration is an interesting addition. On the plus side, it's genuinely useful if you're already invested in the Stream Deck ecosystem. Being able to quickly access macros, shortcuts, or streaming controls directly from the mouse is convenient and can really speed up certain workflows. The downside is that if you don't stream, create content, or regularly use macros, the dedicated Stream Deck button may not add much value and can end up being a feature you rarely use. It's a clever idea, but definitely one that's more useful for some people than others. Very niche. The other thing you need to pay attention to is this is a heavier mouse than most premium gaming mice on the market these days. If you're coming from an ultralight mouse, you'll notice the extra weight right away. It wasn't a dealbreaker for me because the ergonomic shape makes it comfortable to use, but competitive FPS players who prioritize the lightest possible mouse… pretty sure you won’t like this. That and the Stream Deck integration are the reason for a four star review. Don’t get me wrong, if you want streaming options, it works great and I’d say go for it. But if you don’t want/need that and then with the heavier weight, I feel like you’d want to go a different direction. It’s a comfortable, well-built mouse and it’s innovative for the right user. The added weight and the niche appeal of the Stream Deck functionality keep me at a four, but it's still a solid choice for a premium ergonomic wireless gaming mouse.

Good Gaming Mouse - This mouse is pretty decent. It does everything that I would expect a mouse to do with some extra buttons that can be customized for the user’s convenience. You will probably want to set those settings early on, but, if you’re looking for something that doesn’t require any setup, this might not be your first choice. Changing the settings isn’t too difficult, but it’s done in a way that I was unfamiliar with. Rather than downloading an app like some other pieces of hardware, you actually configure this mouse through a site on your web browser. The browser also has to be Chrome-based, so it didn’t work in Firefox. By default, the two little buttons on the top of the mouse (on the top-left if you’re looking down it) are set to increase and decrease the mouse sensitivity [DPI]. While I can see a theoretical use for this keybind, there didn't appear to be an on-screen indicator when I pressed the button. So, if I ever clicked it by accident, my only options were to click up and down through the invisible options while wiggling the mouse around until it felt right again, or I would just have to open the config site again, where it can actually display what the sensitivity is. I used the config to change these into volume control buttons instead, as I prefer a constant mouse sensitivity. As someone who doesn’t stream a lot, I didn’t think I'll get great use out of the “dedicated Stream Deck Launch Button,“ but this is also easily reconfigured into whatever you want. In my case, it became a “play/ pause media” button, and it has actually been really nice to be able to pause YouTube videos that I’m listening to in the background without having to tab out of my game. However, something kind of weird happened with these media buttons. They worked as I described while the mouse was plugged in, but when I went to use it in wireless mode, for some reason it kept trying to open Windows Media Player to do it there instead? I don’t know if this is just some glitch, or if something just needed a restart to work normally, but since I’m going to be using this right next to my desktop anyway, I don’t mind being wired in. As for the other side-buttons, I left them as they were and just bound them in-game to fit whatever game was being played. Usually, this meant a mark or ping for teammates and the like, but it’s really just another button. It is nice to spread a couple of inputs to the right hand, so I’m not reaching across the keyboard with my left hand to hit the M key or whatever. By default, these buttons also act as Page Back and Page Forward buttons in your browser, which is a minor benefit. I never pressed these ones by accident, so it’s not disruptive. I could see a mouse like this being particularly useful for 3D modeling in programs like Blender (if you set it up correctly). The extra buttons can be used as nice shortcuts for navigating that type of interface. The general feel of all the buttons and the roll of the scroll wheel was satisfactory. The clicks have good feedback. I haven’t had any issues with the scroll wheel rebounding (which did become an issue with my previous mouse). The scroll wheel also has a nice bit of texturing on it for a bit of extra grip on the finger. There’s also some texturing on the sides of the mouse, but it’s done in such a way that I wouldn’t expect any meaningful amount of crud to build up over time. It should be easy to clean. The wireless modes do seem to work just fine. You can choose between Bluetooth and a tiny little USB insert, which is nice if you’re short on ports. I didn’t notice any major losses in mouse input either way. The mouse will go to sleep after 15 minutes of inactivity to save battery which could be mildly annoying, but it’s another thing you can change in the config if you don’t mind the power loss. The mouse is supposed to provide between 160-170hrs of battery life out of the box. For hand comfort, it’s mostly fine. I was able to adjust to it from my previous mouse quickly enough. The “thumb shelf,” as I call it, did make my thumb a little uncomfortable at first, but this doesn’t seem to be a factor anymore. The RGB lights are fairly standard for gaming mice, as far as I can tell. You can configure the colors and such in the settings, if you’d like, but I was fine leaving them as they were. You can turn them off completely, if you’re really looking to maximize the battery life. The lights do turn off completely when the mouse (and the computer) are put to sleep, so if you plan on using this with a bedroom computer setup, it shouldn’t bother you at all. The glow does change for a second or two when it gets plugged in, just to tell you that it is, in fact, plugged in and charging. Overall, a solid option with some configuration software that is a bit clunky but functional.

A Stream Deck you can take with you - At this tier, raw mouse performance is close to a solved problem. So much good hardware exists now that a bad gaming mouse is hard to find, and the Nightsword v2 clears the bar easily. 33,000 DPI, 8,000Hz polling wired or wireless, an optical sensor quick enough to track anything you'll throw at it. More speed and precision than most people will ever tap into. What makes it worth a second look isn't the spec sheet. It's the dedicated Stream Deck button sitting under your thumb. I already run a Stream Deck on my main desktop, so the appeal clicked right away. Press that side button and a virtual grid of your shortcuts pops up on screen, wherever you point it, and you're one click from a soundboard, media controls, app launches, whatever you've mapped. For me it means carrying that same control around instead of leaving it chained to one machine. The Virtual Stream Deck normally wants you to own a Stream Deck device or pay for a license, and this mouse counts as the key that unlocks it, so if you'd been eyeing that ecosystem, the Nightsword is a way in. All eight programmable buttons can tie into it too, not just the one launch key. Flexibility is the other thing it gets right. I bounce between a Windows machine for gaming and a Mac for productivity, and it handles both without complaint. Three connection modes cover the bases: the 2.4GHz dongle for low-latency gaming, Bluetooth for hopping across devices, and USB-C if you'd rather run wired or need to top off the charge. Battery is rated up to 170 hours, though that figure assumes lighting off and polling at a normal rate. Push it to the full 8,000Hz and you'll charge more often, which is the trade with any mouse chasing numbers like that. Run it day to day with RGB on and it still goes a good while between charges. In the hand it's light, 89 grams, and Corsair dropped the adjustable weight system the original Nightsword was known for. Coming off a larger productivity mouse, I figured the size might throw me, but it settled in fine. That sculpted thumb rest and right-handed shape stay comfortable over long sessions. One thing to know going in: the Stream Deck button sits right where your thumb rests, and I bumped it a couple times early before muscle memory sorted it out. Not a dealbreaker, just a short break-in. Lighting is tasteful, three zones, nothing loud, all tunable in the browser. And Web Hub means you configure the whole thing without installing a bloated software suite, which is a relief if you've ever fought with peripheral apps. So who's this for? Anyone who wants one mouse that flexes across gaming and work, especially if you're already in the Stream Deck ecosystem or curious about it. The performance is a given at this level, so the button is really what you're deciding on. If a thumb-launched shortcut panel sounds useful, it's an easy pick. If you know you'll never touch that feature, you're paying for a headline you won't use, and a simpler mouse will serve you just as well.
