Keychron K4 HE - one of the most annoying keyboards i've ever dealt with
I bought this thing probably about a year ago. On the surface it seemed like a really good keyboard - I like the form factor and I wanted something wireless. What I did not expect to deal with so much is the buggy firmware. No other keyboard i've owned has this many issues - sometimes I can wake it by mashing the space bar, sometimes the only thing I can do is flip the wireless switch on/off.
Firmware also likes to randomly break on me. Ususally coming out of sleep mode, half the keys just inexplicably stop working and the only way to fix it is to do a firmware reset with fn+J+Z. This usually works for awhile but it seems inevitable that it will always break for some reason. All this combined with what feels like a pretty short wake/sleep timer makes me want to go back to Logitech. I want to update my firmware to see if it's been fixed but honestly given what i've dealt with already - i'm scared this thing will just brick itself if I try to do that.
