I have it, and I LOVE it. My only two complaints are minor...

1. The wii controller goes in the belt that comes with it - and with some of the moves it slides a bit and I have to push it back into the "holster" thing. Mostly squat moves and bends.

2. To find your statistics [i.e. workout times, length, calories burned etc] you have to back out and look under something different, like...options, or something. Then you'll find the stats category. I don't remember the exact path, but it took me a few tries to stumble on it.

So much fun - go for it!
