If you have an Xbox 360, and have wireless controllers, then the Quick Charge Kit will really impress you. First, it comes with another rechargable battery, so that's nice. Second, it allows you to charge the batteries without using your Xbox 360! I know many of the complaints about the first play-n-charge kit was that it used a controller port to charge! No more. This kit plugs into the wall and can charge 2 batteries at once. If you have not yet purchased a rechargable battery for the wireless controller, just get this kit which includes one battery. You will save tons on regular batteries, and it really is a great addition to the Xbox 360 family of products.
