This product (currently temporarily installed - soon to be permanent) has solved my wayward dog problem.Works like a charm. 10 out of 10.

I really did not want to have to use this on my dog, however, since she is a runner, we just had to try it as a way to keep her safe inside our house.. Well, guess what? She got shocked one time and has not tried to run out the front door in over 5 weeks. One day she got close, so I put the collar back on her, and she heard the signal and backed away from the door. This product works like a charm and I'm grateful to have a product that keeps my dog safely inside the house.

We have a black mouth cut, medium size and short hair. This is a good unit.

The one I already had was repaired.

Works great easy to install. Much cheaper than having a company do it!

easy to wire, worked just as expected. Good quality, and I would buy again!
