Praise
“My first better keyboard and I am absolutely satisfied. We'll see how it works after a longer time. I just thought of one small thing, I have nowhere to hide the receiver when I leave with just the laptop and I want to leave the keyboard at home. Like you can…”
Michal V.Verified buyer· via Keychron
Critique
“Beware of the double-clicking issue. I have got 2 units of this. They're both having the same problem and worse.”
