To say our dog is a barker is an understatement. This collar has made a night to day transformation. That is just with it being on no settings being used. We took her for a walk for the 1st time tonight and she is 6 years old.

Great product for the money, easy to use.

This is the 3rd time I've ordered this same collar. Works for large and small dogs. Easy to use and highly effective. Definitely would buy again. Great value.

Had trouble with the initial testing but watched the video and it was my error. Works exactly like it should. Stops her after the second bark on the medium vibration. Much more peaceful for her and us!

I like how sturdy the collar is.

Collar worked great to train my dog to control barking. Can be used with or without shocking my dog, and the strength can be adjusted. The collar also has a vibration feature that can be adjusted. Collar comes with a handy cord to re-charge the collar via a standard USB port.
