It is easy to set up and use. Like that choices can be made for sound, vibration or shock and the levels of sensitivity usage.

My dog is actually frightened of this collar. Once she barks she runs to the deck and won't leave it.

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!
