Good experience

Do some research, there is very little good about this device out there, and almost zero help if any issues are experienced.

It didn't take long to figure out through trial and error, but failing the first few bars of a song while you figure out what buttons do what is not a great user experience.

you just want a Wii controller for Rock Band, expect a great experience

I've had the RB3 keyboard for almost a week now and my experiences are quite good.
