If you use this controller for PC, make sure to calibrate it in your game controller settings. Other reviews mention a lack of joystick sensitivity. This is not the case with the controller sent to me. The joystick has many different sensitivities depending on how far you hold the joystick. It's not from 0% to 100% if you barely click on it. One small issue that was easy to fix was that I took out the batteries while it was on and plugged it into the dongle. When I put the batteries back in, all the buttons were reconfigured and didn't work properly. When I looked at the game controller settings in Windows, it was no longer recognized as an Xbox360 controller. Instead, it was just a wireless game controller. The simple solution was to remove and reinsert the dongle. Everything has returned to normal. I've played over 5 hours on a single charge and that's a conservative number. I have several Energizer batteries.
