Charged quickly and put in my controller with no problems, played a couple hours and is still at full charge. Everything seems to be made of decent quality. Which is impressive for the price. Worth it to not have to replacing the aa batteries in the controller
The product is alright. It's a pretty good price for two Xbox360 battery pack and charger that lasted least 3 or 4 hours. The Charge lasted least 30 mins. I am not sure it's good as Mircosoft's XBox360 Batteries and chargers but it works good.
