Specification :

An important measure for good accessory is whether it adds to the gaming experience or not. This one certain does. Not only is this more comfortable than holding a Wiimote naked or jacketed, the wheel itself is just fun. It's just so entertaining to swing the wheel left and right like a madman. Built with durable ABS plastic, this wheel's got a decent weight to it and will certainly last the same if not longer than your other Wii accessories.
Getting the Wiimote into the wheel really isn't any problem at all. Just take off any jacket or sleeve your Wiimote may be wearing, and slip it in. Four grips in each corner hold the Wiimote in firmly, and taking it out of the wheel is as easy as pushing through the hole in the back. The wheel also carries the rumble perfectly.
Every function of the Wiimote is available when in the wheel except for the expansion port. Players can even navigate the Wii menu with the Wiimote in the wheel thanks to an IR port on the left side of the wheel.
The B button extension on the back fits perfectly over the Wiimote's counterpart, with no gap in between. Even the wrist strap comes through the hole in the back.
