Insanity question..

happinessforevercm

For those of you who used insanity I was wondering if I can get some feed back. How did you like it and did you get the results you were hoping for. Also, I was wondering if you had to buy extra things along with it, I am going to convince my hubby into letting me get it but at least I will know about how much it will cost.

Thank you all for your help in advance!
