“I love the sound, the keyboard was shipped fast, but i have found some of the keys have input issues at times where it doesn't register the key being pushed”

“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.”
