In short, they rock! I'm not going to go into much depth because I don't think they are made anymore, but they work just as well as the Wavebird. I was just playing Smash Bros with my friends and two people were playing with wireless controllers, and two were playing with wired controllers and we placed just as we normally did. The battery life seems good, but my only complaint is that the joystick is bare plastic. I would have like it to be rubber like the first party controllers/
