Review on Controller Charging Rechargeable Battery Batteries by Steve Brethorst

This only works with 1 of our 4 controllers. We only use our Xbox for movies and TV apps, so having only one controller doesn't bother us. It worked great for about a month and a half, now it doesn't even work with this controller. We bought new controllers to see if that's the problem. We've concluded that it's not the controllers, it's the charging dock. It is very easy to use and when charging the controllers, the battery life was longer.
