Nintendo Wii MotionPlus Adapter

This piece of Wii accessory attaches itself to the rear of your original wii remote control along with the accelerometer and sensor bar, to track the player's arm position and orientation with precision and immersion. This Motion Plus for Nintendo Wii adds more fun and well defined motions and positions to your game.  *Note: Some later model Wii Remotes have MotionPlus already integrated into the controller. Look at the bottom of the front of the controller, if it is integrated there will be a MotionPlus message printed there.
