Praise
“Bought with super banana switches (awesome if you like panda switches!). The only complaint I have is having to plug it in to change any settings. Why?”
NickVerified buyer· via Keychron
Critique
“Pretty much right out of the box it started registering double letters when typing. To the point where I’m fixing every other word I type. Very disappointed”
