Wii Nunchuk Controller Contoured to perfectly
fit a player's hand, the Nunchuk controller builds
on the simplicity of the Wii Remote controller and
goes an extra step to meet the needs of gamers.
The Nunchuk controller connects to the Wii Remote
controller at its expansion port and is used in
conjunction with the Wii Remote controller.
Note: All US and Japanese Nunchuks are 100% compatible with US Wii systems.
