I had no problems, thus far, with this product. It's not the main Xbox 360 rechargeable battery pack, but it is suffice. The only, nitpicky, thing that I noticed is the color difference between the battery pack case and the controller. The battery pack was a darker white than the controller, it's a noticeable contrast offset but it's not something I would be irate over. As far as the overall charge the battery pack holds, it's lasted me a good amount of time. I have yet to really sit down for a day and play a role playing game that takes up a lot of time, not World of Warcraft amount of time, to see how long the charge lasts before its drained. The charge cord is USB and roughly a foot or two long, not an antiquate length to try and play while connected to a USB port either on your computer or Xbox 360. Plus, I haven't tried playing while the charger is connected... I don't know if that may or may not adversely affect the pack. Overall it's a satisfactory product, but a great product if you're sick of buying new batteries all the time.
