The Xbox 360 play and charge kit is the best this allows to continue playing your game as the controller is charging. This kit allows your controller to be charged for up to 30 hours of playing time. That would take like 4 batteries which to buy that pack of batteries cost some money. Also this kit comes in two colors white and black so that it can match your xbox
Without the play and charge kit you could waste hundreds of dollars worth batteries on your controller that will just eat those batteries so fast like they were nothing. It doesnt cost that much and a real active player would spend more then the amount used to buy this on batteries in a month. This kit will last you a couple of years before you acctualy need a new battery and by then there will be much bigger and better game consoles out there to buy.
So why spend more and more money that only go to waste on your xbox controllers when you can get the charging kit that will last you years. I would diffenetly recommend this to a friend and other gamers.
