Wii Motion Plus technology is the new standard for Nintendo Wii videogames. Gyroscope technology has been incorporated into the adpater to provide quick and responsive rotational motion recognition. This means that the remote will have near 1:1 motion sensitivy, improving the accuracy of your next golf swing or sword stroke! Simply plug the adapter into the bottom of any standard Wii remote to upgrade it to a Motion Plus enabled controller. Motion Plus enabled controllers are required to play Motion Plus Wii games, and are compatible with all non-Motion Plus games. The adapter features a second, built in extension port to connect your nunchuck attachment. This is a generic product, but the quality is on-par with its name-brand counterpart.
