If you whant to keep playing and you dont wahnt to ahve lots of old batteries liying around this is worth every penny...
If you play a lot yull need this accesory

Saving is what calls out the most in this product, specially nowdays, when we've been talking about saving nature from chemicals.

This rechargable pack is fantastic. The savings on batteries is amazing. Charges within two hours. I have three of them for my sons and I would recommend them for anyone with multiple players in the household.

This is a given, if you own an Xbox 360, buy these battery packs. I know we can complain how they should come with the system, and having to purchase them is a ripoff. Seeing how Sony's controller comes already with a rechargeable battery within it. However, unlike the shameless ripoff that is the $180 Xbox 360 120GB hard drive, the $12 price for this handy item isn't so bad.

For me, I usually replace them once a week, and I'm a moderate gamer. It has no effect on my gaming though, cause it only takes an hour or 2 to charge on the charger, also sold separately. They are easy to swap in an out, just a click and swap. As far as longevity, we have had the white ones since the first Xbox 360 came out. Meaning, we have never had to throw any of these out in two plus years. Just imagine the cost of batteries, and the impact on environment that would have if you chose not to get this. Sorry to get preachy, we live in Portland after all.

Not much too say other than it looks better than a white or other color battery in my granddaughter's controller.
