Review on Enhance Your Wii U Gaming Experience with Nyko Uboost - Unleash 2X Power for Extended 10 Hour Playtime! by Dan Dickey

The battery life of the Wii U controller is terrible. You feel like you barely enter the session and she dies. So I looked for a solution on Amazon and finally found it. I doubted the first reviews but decided to at least try. It was very easy to install, but it definitely adds weight to an already bulky controller. Nothing crazy, but noticeable during long games. I feel like I spent about 6 hours or more on average which is more than I got so I can live with that. It also fits perfectly with the Nyko charging dock as shown in the photo. Time will tell if it will continue to work, but so far so good.
