Well worth the money. It reminded me of some of the little things to be sure my pup got exposed to that I might not have remembered. Add it to your library of training materials. If you pick up a few points that improve your training, your money ahead.
If I were a pro waiting for a clients puppy, I would make sure they had a copy and encourage them to complete all the exercises before delivering the young dog for training.
If I were a breeder I would send a copy home with each puppy.
As an Amateur, I was really impressed with the agressive nature of the program and was still struggling to complete some drills when the pup was a year old.
IMHO, it's probably the best money you will spend.
Best of luck to you and your pup!
