Praise
“This keyboard is designed to work with windoz and Mac. But I can't find Apple replacement keycaps anywhere. This is the only reason it gets 4 stars instead of 5.”
Jeff E.Verified buyer· via Epomaker
Critique
“Screen - it's pretty decent for the price, it works as long as you don't customize the GIF or the JPEG as the software DOES NOT WORK .. it will say it's updated or the screen was updated with the JPEG or GIF you choose but it will only show a white screen …”
