We own one.
I like that my daughter is up on her feet while she is playing video games. It gets kids more involved and has some value to it, in that it requires some movement. But as a fitness plan, it is really pathetic.
I do not mean to say that a person can't improve with a Wii Fit. I'm just saying that there are far better ways for a person to shape up, that will be a lot cheaper and more effiecent.
In other words, if you are going to buy it for fun, you might as well get one. Your family will at least move around rather than sitting on the couch. But if you are looking for a fitness plan in-and-of itself, I'd look elsewhere.
