Praise
“I love my new keyboard. It is as quiet as advertised and I’m very pleased with the overall performance of the keyboard!”
Jean P.Verified buyer· via Epomaker
Critique
“I have no way through the software to keep the keyboard on for more than a minute. And randomly throughout typing or gaming the keys become unresponsive. Id expect that out of a 20$ keyboard. But this was a 100$ purchase, very dissapointing”
