Keychron J1

“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…”
“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…”

“Perfect addition to my Nuphy Air75 v2. The keys line up well, and this gives me a knob and 10-key when I’m at my desk!”
“The K0 MAX is just right with its red Gateron switches! Typing on it feels really natural. 2 Stars less because the battery needs to be loaded again after 3 or four days of occasional usage.”
