Praise
“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.”

Critique
“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.”

“Amazing build quality and sound. The Keyboard is visually and audibly very appealing. The correct QWERTZ DE layout made the decision to get this keyboard quite easy.”
