This product does exactly what it is supposed to do. It charges two batteries quickly and efficiently. The batteries fit in perfectly and while only one battery comes with the charger it will last longer than the two third party batteries that come with other chargers. I highly recommend this charger to recharge your batteries, as opposed to the charge and play cord for four reasons. 1) It is much faster to charge your batteries, 2) You don't have to be tethered to your 360 while you charge, 3) You can charge two batteries at once and finally 4) You don't have to have your 360 on to charge the batteries.
