--What is it?--
Well, it's probably pretty obvious what this is but let's explains anyway. The Wii controller comes with the Wii console. It is a motion sensing controller than looks rather like a television remote. It is connected to the Wii console using infra-red.

--How to use it--

Using the wrist strap, the controller is securely fastened to your wrist to stop you from dropping it or throwing it towards the TV. I've seen plenty of pictures of smashed TV's caused by the controller, so it's best to use this! You then move the controller around while pointing at the TV to move the curser around. Depending on what game you are playing, the action you are required to do will change such as shaking it or using it as a golf club, tennis racket etc. It can also be held while you are running on the spot or dancing to zumba and will then takes your score according to the movements.

--What can be used with it?--

There are many things that it can be used with such a nanchuks. Though I have never used this, this will be inserted in the bottom of the controller via a wire and the nanchuck will be held in the other hand. You can also place it into a plastic car wheel to then play driving games such as Mariocart. I think the first one you should buy if you are thinking of purchasing any extras is the grip. This is like a sleeve that is placed over the remote and attached at the bottom. This makes it easier to hold as well as being much more powerful

--Would I recommend it?--

Well if you have a Wii console, it certainly is an essential part! ;)
