An outstanding piece of hardware considering its cost; I purchased it together with a charger for two gamepads straight away, and I haven't had any issues since. Because the battery has a capacity that is far lower than I need for a period of two days, I found that playing a lengthy game was sufficient. After that, I had to stop playing because I neglected to charge the device. The benefits of it include: Conveniently, once I used it and then arranged for it to be charged, the gamepad is always fully charged. There are also 2 batteries supplied. Having this drawback: When charging, it does not significantly correct the gamepad. It is preferable to place it in an area where no one will be harmed.
