“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.”

“Amazing. Love the weight, keycaps, color. Knob placement could be much better. Spacebar leans to one side since I always press it on the right and gets uneven.”
“Keystrokes doesn’t have light instead a rainbow where i can’t focus when typing”
