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”

Praise
“Keycaps are dyesub, but still PBT Tactile switches feature a proper tactile feeling with great typing experience The case feels and looks really premium layer activation could be nicer but in the end you just gotta get used to the board”
