Loving the Wii Fit

I have the Wii but the Wii fit, but I need to know before I fork out the money how well does it work on carpet? I have carpet throughout the house and I would like to know if it matters if it's on carpet or needs to be on hardwood floors. Any thoughts?

Works fine on carpet.  There are extenders you can put on the bottom if the carpet pill is to high to even it out.
