There is a new litter training system by Purina for dogs. Has anyone used this and recommends if this works?

I don't recommend it because it proves that people are lazy and won't take the time to take their dog for a walk or let them go out for a potty break and exercise. This just encourages bad dog owners and is one more reason that people will start complaining that their dog has behavioral problems because the dog does not get a chance to go outside and play.
