JM's 6 week 6 pack

I am currently doing Insanity and only have a week and a half left. I was thinking about doing my 6 week 6 pack by Jillian Michaels afterwards and I am wondering if anyone has gone through the whole 6 weeks and if so, what were your results? Were they good, great or not so much? I just want to know if it is worth my time if the results are minimal. I will do something else.

Thanks!! ~Neecy
