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
“Screen - it's pretty decent for the price, it works as long as you don't customize the GIF or the JPEG as the software DOES NOT WORK .. it will say it's updated or the screen was updated with the JPEG or GIF you choose but it will only show a white screen …”

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…”

“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”

Critique
“I made an order for EPOMAKER x AULA 75 with express shipping on 27/1/24. Emailed the team TWICE. Now its 19/3/24, and i still dont have the item. Very poor service”
