Insanity - to buy or not to buy

BrenB150

I have been kicking around the idea of getting insanity, but i dont want to spend the money if it is not all the great.. Can i get some advice on:

If you like it why?
What don't you like about it?
Average time for each dvd?
Are you seeing results?

Thanks for everyones input.. I dont want to spend the money to just add to my collection of dvds i dont like.. I do dvds.. If i like them..
