Recently bought this power pack for my new xbox 360 slim knowing that with Black Ops coming out I would need all the battery life I could get. I was tired of spending money on batteries that died quickly but with this power pack the battery life is much longer and when it gets low just plug it in. Plenty of length on the cord so it will reach pretty much anywhere, well put together, and the DreamGear logo on the battery spices up the look of your controller. Very please with my purchase
