I bought it. It's okay. It does actually have some moves I haven't really seen anywhere else, and they're reasonably challenging, too. It has three workouts on it - each is about 10 minutes in length. Or you can do them all in order. It's nothing to rush out and buy, but if you need some extra ab work, it's okay to have. That damn Bender Ball sure was waste though! I forgot I even have it.
