Get Wireless with your Wii with the Nyko Wireless Nunchuck
Here is a cool controller for your Wii, the Nyko Wireless Nunchuck.
The Nyko Wireless Nunchuck connects too the Wiimote via a wireless dongle that plugs into the controller’s accessory jack.
Once you have plugged it in, you tap the connection buttons on the dongle and the Nunchuck syncs them together, letting the Nunchuck work as if it was physically connected to the remote.
The Nyko Wireless Wii Nunchuk will go on sale later this month for about $30.
