We're using the system on our third dog and have had no problems to date. It's a little time consuming to train your pet to the system but if you have committed to owning a pet then you should have no problem with this. The one tip I would share with future owners is to be careful of the intensity of the shock. Too high and your pet will be afraid to leave the house...too low and a stubborn breed will have no problem running right through it. All around a very effective product.

Pros: Works great after the dog is trained.

Cons: A little trying with a stubborn breed and a very time consuming training process.

This just didn't work for us, Luna would run through it and then not want to come back

Pros: useful for some dogs

Cons: not for mine
