No problem yet

This controller works great. I have had a couple crappy game pads before, this one is the only one that hasn't disappointed me.

Other reviewers have complained that it is unreliable, but I can't comment as I've only had it a few weeks. It has done a super job for me so far, including having my wife play Psychonauts and jamming the left analog controller almost as hard as she can the whole time she's playing.
