I think it's good. I haven't had it very long, but I enjoy it when I need a short cardio workout. I don't have the videos that she used to make this (Step Blast, Step Jump and Pump, and Kick Punch Crunch), so for me it's fun. I also have the CTX and that one is talked about more, I think, because there are more workouts on it, and some real killers like Leaner Legs.
