Praise
“Overall good little keyboard for the price, other 40s cost more but better quality, also I could not find a few characters mapped on this one, not in manual or online.”
pstraghanVerified buyer· via Epomaker
Critique
“The keyboard is very solid ooverall, but frequently will type two letters instead of one on key press. This is a very frustrating issue and leads to many typos. Without this problem, it would easily be a 5-star keyboard.”

Praise
“Keyboard sounds nice, works nice, the software is a bit of an issue to set up as there aren't any proper instructions but you just need the drivers and the VIA app.”
