The Wii Balance Board is an innovative accessory created for the Wii™ Console. As you step onto the board, it interprets the movement of your feet and brings your motions to life, just like the Wii Remote™ controller. By sensing your weight and balance, an incredibly accurate control scheme is possible. The Wii Balance Board provides endless ways to turn your Wii experience into a much more active one! Comes with 4 extensions and an operations manual. Used only a handful of times.
