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. :-)

I'm very happy with this product!

Great product, great service, what more can you say?

This is a great collar.

Instructions are easy to use / understand, reasonably priced, fantastic customer service. To us, that's an excellent value!

Purchased this collar to help train our strong willed Golden /Lab mix. I was hesitant, but after using this collar found it extremely helpful and easy to use.
