Love it. Saves me a lot of money in the long run, I don't have to go out and buy batteries anymore. My controller used to die every 2 days but now that I can charge it when I'm not playing I don't think it dies. I've been using this for over a month now and I love it. You can charge the batteries when they are in the controller or when they are not, but this is less sensitive when they are in the controllers. I would definitely buy another one if I had more controllers. Good product.
