I dunno. It works OK for me (and I use a cheap off-brand USB cable that works fine for me). I keep it plugged in, so I don't really care about wireless or Bluetooth.
Like I said, I am not really fanatical about keyboards. I wanted the RGB backlights, relatively tactile (but not super -I use red keys), and fairly small. I also wanted wired. This is wireless, but runs as wired.
It seems to be a common frame. I think I have seen almost identical port layouts in other brands.
I brought it about a year ago.
Also Keychron had some obscure usb cable requirement, that they could never convey over support emails. You would think that any usbc usbc cable would work for a keyboard, but not the few I had laying around that were longer than the provided one
Just my two cents, I wouldn't buy another Keychron
Maybe their QA has fallen in recent years?
My mk journey went das keyboard > cooler master > leopold > vortex > keychron. I haven't looked for anything different since I got the keychrons.
I'm not a keyboard geek (I don't touch-type, for one thing), and feel you, for the "one-stop shop" thing.
I do have a couple of old Logitech keyboards, collecting dust in a bin, upstairs.
