Has anyone tried Bootcamp: Maximum Calorie Workout?

It's by TheFIRM (http://www.firmdirect.com/firm/p/TheFIRMBootcampMaximumCalorieBurn.html)

I found this somewhere in my house by I've never used it before... I want to know if anyone else has used this and if their results were good :) If not, could you please recommend others for me? thanks x
