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.

Works very effectively on one dog with no pain or discomfort. Second dog is a bit wiser, would be good to have settings for the bigger stronger dog. Recommend though, it has made a huge difference.

I did not receive the left light that is listed in the description. The collars seem to be working and look as described.
