I would love to say that this controller is excellent, for I truly wish it was. It is certainly much more rewarding and fun to play than the normal controllers. However, I've owned three and each of them has had one small fault or another. In one case, the whammy bar was always registering as slightly pressed so that all long notes were pitch-bent down. On the second, one of the buttons fell off. On the third, it has a similar whammy bar issue though less severely. However the paint is wearing off of buttons.Still, I own one and enjoy it.
