It's a very good go-along with the book. You get 5 DVDS for 100 dollars, which is a pretty good deal conering the amountof material covered. Dave is a good teacher, and his style translates well to learning through a DVD. I give it 5 stars. Definately good to help your stand up game if you're mostly BJJ, and also good to help you're ground game if youre Judo.
