Work well. Not made as good as the really expensive ones but they do the trick

Dogs listen better. Does not have to be on. They hate it. Very rarely turn it on.

We have a Jack Russell mix, all sorts. Extremely cute, but very highly strung. She will literally bark at nothing, constantly, driving everyone crazy

I saw a similar dog training device from a professional trainer. So I also bought one. With the multiple modes available, it has helped in reducing the frequency of its barking. My dog really responds well to the vibration then anything else. I didn't have to shock her. Very easy to set up and use. A good value worth trying. Well made and less than half the price of the one the trainer offered. Be sure to test it on yourself before using it on the dog. It came on at 100. Gives quite a shock. Recommended turned it down to below 35....

I received this product to review and I'm glad I did. We have a German Shepherd that doesn't always like to stay on our property. This worked great for alerting her that she needed to come back onto her property. I have not used the "shock" feature because I do not want to scare her. But the beeping feature was great

We do not leave this collar on him beyond two hours.
