Rules this board out

  • South-facing LEDs. Shine-through legends stay dark, and some sculpted keycaps can clip the LED.
  • Compact full-size layout. The numpad is present, the gaps of a full-size board are not.

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”
CJVerified buyer· via Epomaker

Praise
“I like everything about this keyboard: the keys, their profile, the typing sound of the banana switch, the shape of the keyboard itself, and its size. There are no battery issues either; it holds a charge surprisingly long, and I don't remember the last time…”
Maks B.· via Keychron
Critique
“Almost perfect keyboard for me, low profile, etc., but battery dies too fast, i'd say 2-3 days max. and when it dies it does not reconnect when charging cable is plugged in, you have to toggle wired mode, plug in the cable and then toggle wireless mode for it…”
