“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”

ElijahVerified buyer· via Keychron
Critique
“I bought this keyboard in March 2023 and genuinely liked it at first. It's solid, heavy, well-built, sounds great. Keychron clearly knows what they're doing in terms of design and firmware. The problem is the switches. After about a year and a half of normal…”
