Worked for a few months but now it's not working. Last month, our Xbox 360S shut down randomly. I figured it was just overheating (even though it was in a cool room) so I cleaned it out with canned compressed air. Today the Xbox would turn on for a split second and then turn off. We have a second Xbox 360S so I plugged it in and the same thing happened. I took the power adapter (original when we bought it) from the second Xbox and plugged it into the first and it worked like a champ. So I knew it wasn't an Xbox, but it was the device that isn't working now. At least we got some benefit from it, but I'll buy the real thing so I don't waste money on such imitations anymore. He died just a few months UPDATE: Had no issues with another supplier replacing in the last year.
