Praise
“This keyboard is designed to work with windoz and Mac. But I can't find Apple replacement keycaps anywhere. This is the only reason it gets 4 stars instead of 5.”
Jeff E.Verified buyer· via Epomaker
Critique
“Launching a game makes the board thinks it switch to Mac mode, swapping Alt and Win key. This is random and will usually happen when launching a game. The only fix I know is to unplug and replug the keyboard over and over again until it thinks its in Win mode…”

Praise
“Love the sound and feel. Thr kickstand is cool too. Only thing is I wish there were more options for keycap colors, the red doesn't match my stuff.”
