This device does NOT let you connect your wireless controller to a computer – don't be fooled by the other reviews. This cable charges the included battery ONLY – the connection to your 360 is still wireless, no data is carried over the cable. You can use your pc to charge your controller using this cable but you CANNOT connect your controller to your pc to play games on your pc using only this cable. You need to get a wireless receiver for PC in order to use a 360 wireless controller with your computer.

Excellent! Well worth the money and definitely pays for itself in no time. I have had mine for more than 1 and a half years now and have not had to buy batteries once. Very easy and convenient to use as well.

This is probably the most handy accessory except for the headset. Instead of waiting to charge batteries you can charge the battery pack while you play. its so good. I used to use multiple battery sets and it used to get annoying cause id forget to put them on chage or lose them. this i just leave the battery pack in the controller and i just zap the cable in and it does it for me.
