Summary: Firstly, I love this controller for what it does. DJ Hero is great, and the mechanics are wonderful; even if the slider is a bit too touchy when it comes to returning to center. The problem with the controller is that, while they feel heavy duty, they definitely aren't. The turntable itself can stop recognizing motion after a few months. And the slider can stop functioning properly as well.
Summary: When I bought the game, I wasn't expecting it to be as fun as some of the other games with it's objectives. After playing it, I was instanly addicted. The only problem I had was not with the game, but with the controllers. It came with two controllers but after only one day (a few hours) of use, the dongle that connects the turntable to the system stopped receiving a signal.
Summary: Was great when it worked.... After approximately 20 minutes of use the white turntable refused to sync. A quick google search indicates that others have this problem, and not just with dj hero tables but with rock band equipment as well. The grey turntable works great and syncs every time so I can still play solo, but the whole reason I bought the party pack was so I could play with friends locally. Buyer beware.
