This is a genuine official remote.
Using Bluetooth technology, the wireless Wii Remote controller sends your actions to the Wii console from as far as 30 feet away. As a pointing device, the controller can send a signal from as far as 15 feet away. Up to four Wii Remote Controllers can be connected at once, making for some great multiplayer fun!
In addition to its pointing and motion-sensing abilities, the Wii Remote controller also includes a speaker, rumble feature and expansion port for additional input devices, such as the Nunchuk controller.
