It works like a charm i have a 75 pounds pitbull and he is really obedient .. and a good boy too but when off the leash he would of want to say to everyone and not everyone wanted to be great by a pitbull understandable !!! Installed this is my yard / front of the house and now he wont dare to go say hi to any one!!! One week of training with him also getting snap!! Lol grate product!!!

Definitely would recommend!

Works great. My dog no longer wanders. I like that I can select a correction level that provides a tone but no shock. It does the trick and if my lab decides to ignore the tone, I can set the correction to include a mild shock.

Wonderful product, that's not what my dogs would say because they can't get past it. We love it we have two full size dogs and a cat. The cat gets to travel around in the front yard and the dogs get the run of the back yard and non two shall meet. Easy to install and works like it says it will.

after using it just a couple of times he now will stop barking when we give the command “quiet”. we love it!

It has a super long battery life, and you get to choose between noise, vibration, and shock. We have only needed the vibration mode. we love it!
