Query: The weak link in the wii system.

The wii nunchuck makes me regret ever buying a wii system for my children. We've gone through about 10 of them in two years. They work for a few months, then you need to buy a new one. So basically we can keep buying nunchucks or we can have all of these expensive games our children can't play. Great choice. Don't buy wii.
