Memwah Wii Motion Plus MotionPlus Accessory Addon Controller for Nintendo Wii Console - White

This controller acts as an essential secondary to your main remote, adding even more innovation to the next generation of gaming, and does it all with less physical movement. Used in conjunction with any Wii remote, certain games need the Motion Plus controller for additional control options. The Motion Plus controller builds on the simplicity of the Wii Remote controller. The Motion Plus contains an enhanced, more accurate motion sensor found in the Wii Remote - allowing for more accurate, improved play on some games! Also, the Motion Plus controller doesn't need its own power - it plugs into the Wii Remote controller when it's in use. So there's no need to worry about charging or replacing expensive batteries.
