Great 360 battery pack...6/9/2012
For the money, the Nyko 360 battery packs work every bit as well as the first-party Microsoft brand. They fit well into the controllers (not always the case with other 3rd party packs) and have comparable battery life. All-in-all, if you're looking for an alternative to Microsoft's overpriced packs, this is the way to go.
