Overall a good one - Really good quality but hard to get used to it especially with large fingers

RyanAug 14, 2025 · Verified purchase ★★★☆☆

Possible skip for Mac Owners without USB-A - Feels pretty nice to type on but takes noticeable amount of time to connect when using bluetooth. Would disconnect almost immediately if screen went to sleep. Oddly it uses a USB-A to C cable which would be fine but then its adapter is a double female A-C as well which makes it useless on newer Mac’s and the 2.4ghz receiver is also USB-A.

Nice little Keyboard! - Great keyboard for those needing a small form factor.

Pretty good. - I just wish replacement keycaps and switches were easier to come by. Keyboard itself works great. Wireless is hit or miss.
