The vibration alone really helps my dog understand that he is doing something wrong. The shock definitely works!

Would definitely recommend... I haven’t had to use the shocker yet. The sound and vibration alone seems to make him listen. The battery life last about 2 weeks before I have to recharge it.

Works like a charm for excessive barking! Very satisfied. I love having the 3 levels of discipline to help train the dogs.

The works great and has a longer battery life than other brands I have purchased. I love that you can control the vibration strength.

Lock button is a plus, battery lasts forever, vibration strength is more than enough for your dog if my dog can feel it and it's on level 2 out of literally 100!

Out of the box I had immediate response. My dog was out of sight and not coming when called. One short hit on low he was at the back door. Good quality and easy to follow the directions.
