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…”

Praise
“Bought it, even if not available in german QWERTZ Layout. But because of reprogrammabillity, that does not matter that much. The clickiness of the brown switches is on point. Big fan. I would really like to have not ansi style buyable Low Profile Double Shot…”
Christian H.Verified buyer· via Keychron
Critique
“The form factor is great, the board feels great to use, but unfortunately it drops inputs far too frequently. I bought the board about 6 months ago and it was immediately dropping inputs, it didn't happen frequently and I hoped it would get better. Keychron…”
