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.”
