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…”
