The key was to have the ability to shock our dog when he barked. With the other collars that were automatic, our dogs were smart enough to figure out how to position them and avoid the shock.

This one finally fixed our barking problem.

This product is absolutely fantastic for what it is designed to do.

Now that is fantastic customer service! I give this product AND company my highest rating!!!

Excellent product… Does everything that it says it does. Very happy with this purchase.

This is the first time I had to use a training tool like this. The instructions were easy to follow and the training manual made it even easier to understand in the dues and don'ts of how it works. My German Shepherd puppy who weighs 70+ pounds definitely understands now when I say "no"!!!. I would definitely recommend this product as a tool to train your stubborn puppy/dog. I would rate this product five stars out of five. :-)
