I have a number of the firms dvds and have been using them for two years with great results. Bought this thinking I would step it up a notch but, the cueing is so bad you end up stopping to say WHAT!! The most disconcerting thing is that the steps are off the beat of the music and that drove me crazy. It's a tough workout if you can get in your own groove but I find myself using this the least of all the Firms workouts.
