Ajazz AK820 Max

4.3

16 owner reviews

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…”
Mochi· via Epomaker

Praise
“It's a nice keyboard, has a nice sound when typing. I like the dedicated volume know and it's easy to load gifs onto the little screen using the ajazz software”
David C.Verified buyer· via Epomaker

“Works exactly as intended and still works as new. The 2.4 GHz Receiver doesn't communicate correctly and isn't reliable but on BT and Cable it works perfectly”
