I bought it with a try and see attitude. I didn't expect that the effect was so good and the sensitivity was very high. When I adjusted the vibration mode, it was only a slight vibration, which would not hurt the dog. In the past, the dog would bark at random as long as there was a sound, but now it is much better

These work Great for our small but BARKING Terriers!! Vibration & Sound did the trick, with NO Shock needed!!

As described, a bark stopper can vibrate or make sounds to stop a dog barking.My dog, who always screams in the middle of the night and is constantly woken up by him, has a poor quality of sleep, so I bought this barker to correct his behavior.Now that the results are in, the dogs still need time to get used to it.

Super simple to set up and charging was relatively quick.The review gives me an option for remote rating... Mine didn't come with a remote and I was expecting one because I don't believe this modle was supposed to have one so I don't know what that's about.

Works well for a pit bull mix and a beagle mix, it’s easily adjustable for each size dog.

I have 3 Shelties. The barking was awful. Bought them each one of these collars & it stopped 2 out of 3 dogs barking immediately. The 3rd is a little tougher but she has definitely improved.
