GiovaniOct 20, 2026 · Verified purchase ★★☆☆☆

I was SOOO Hype for this - Non-stop disconnecting. I tried with the 8K Mouse Dock V2 Pro and with the dongle that comes with the mouse, the dongle works much better but still disconnects within 30 minutes of gaming. I believe this can be fixed via firmware update because what's happening is the sensor stops working until you power cycle the mouse while the scroll wheel and buttons actually work still. It's bizarre that this wasn't caught during QC. I gave it a second star because IF it were working out of the box for me it would've been the greatest mouse I've ever had because the way my bigger hands grip the body and the additional buttons they added over previous versions of this mouse bringing it essentially on par for me to the Logitech G 502X Plus I have. You might also not like the way the scroll wheel options have an audible click to them when you switch through the different modes and the "infinite" scroll starts, sounds weird and unnecessary.
