Praise
“Great keyboard. Love using it. Two quibbles: Logo is backwards on Windows key Wish Caps Lock lit up—the LED underneath isn’t enough to indicate when Caps Lock is engaged.”
Andy D.Verified buyer· via Keychron
Critique
“I have never used a keyboard where every time you just as much barely graze a key' it registers. This is horrible, you pretty much have to perfectly press the keys dead center, otherwise, it will press surrounding keys as well.”
