3600 mAh Rechargeable Controller Battery Pack for XBOX 360

Drunk one night and I apparently bought this along with a couple other brand batteries for the xbox 360 controller. This was the worst. It does NOT use the microsoft cable to recharge. It has a separate pretty short USB cable that plugs in the backside of the brick instead and wouldn't let me play while charging. The device takes forever to charge, and does not hold charge long at all. There was no sealed plastic case as shown in the picture, instead the battery and cable arrived in an unsealed box. Therefore, the device could have been used for all I know. I give it a rating of 0/100 and recommend you stay away from this product.

Pretty much what the above poster said. It was ok at first, but after a couple of months it stopped holding a charge for more than a few minutes. Don't bother.
