I saw the commercial about this last week and it seemed to be good. With that I just now did a search regarding reviews about it. Practically every review I read (from all diff. sites) were positive.
They said that in 10 min. you get a really good workout and that the next day you do feel it. They also said that if you do several of the workouts, which they call "stack" you get even better and quicker results.
The only complaint I read about this program was the price. They say its 79.99 (which I don't think its a bad price, if it does really work).
I'm not an exerciser, so a 10 min. workout appeals to me. All in all what ever I read was positive, I just don't know anyone personally who did it.
