“This is my first time trying "barebones". Im just blown away by the build quality. It is very heavy! But thats something i like about it, nothing you wanna carry around in a backpack on the train anyways. I picked up Gateron G Pro 3.0 Brown switches with it…”

“USB is working for me, but I have it plugged in to a USB switcher. I haven't configured the keyboard, beyond the switches in the back. I'm liking the keyboard so far.”
“USB on keeps dropping out, even after firmware update (1.0.2) and reset. Tried multiple computers, windows and Mac. Half the time it doesn’t work at all.”
