Negative Positive
Title: It really works!
Review: I was skeptical, but bought it anyway. I'm really glad I did. We have neighbor dogs that stand at the lot line and bark hysterically at us when we are out in our yard. One press of the button, and they turned around and walked away. We have used it several times , and now they seem to stay away. So far so good. Minor problem-the back doesn't stay on very well.
