Works brilliantly on my very stubborn dog. I've used these for years. Never been disappointed

Training aid that works without harm.

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....
