The wheel for mario kart is great, lot of fun, great for kids and adults too. Much more fun than using the wii mote and the nunchuck, but not quite as easy! worth having though.
|The official wii wheel is far better than the third party ones that are being sold as it has the button on the back for firing weapons. (and usually is the same price!!!) so I would really recommend buying the official one. Be careful as some sellers are advertising the official wheel but that isn't what they are actually selling, and I had a bad experience with this as the photo ad the description wasn't of what was sent to me!
But if you can get the official one then its well worth it!
