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…”
