“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”
MegaNoobyYTVerified buyer· via Epomaker
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”

“Feels great, haven't got a new KB since my Novatouch. Great high end features and feel, DSA caps on it feel good.”
Paul B.Verified buyer· via Keychron
Critique
“The dongle does not work after 6 months of using it and they want me to pay to fix it. If you want to buy a keyboard that is good don’t go for keycron”
