As mentioned in the title, the battery has a very good performance and felt even better than the original (but have not tested it). Must recharge it relatively rare. Unfortunately I did not make any long-term experience with it, so I can not comment on the durability. 1 star deduction, for embedding the battery (manual simply search the Internet). The reason is that the installation is a little fiddly. This is because the original battery on the sides has small holders, with which one can befestigegen this during installation easy, while the battery does not have these brackets and slides for this reason when fitting back and forth. Do not worry, however, after the close of the controller is heard no rattling or the like. The battery sits firmly then.
