Title: surprise! it works!
Review: The unit is like others have stated; once the battery goes in, the back cover does not fit. Oh well. You push the button and while the little light goes on, you cannot tell if its doing anything else.Having said that, it's been 4 weeks, and the neighbors dogs totally get quiet when I hold the button! They stay there wagging their tails, it does not seem they are in any discomfort. They simply stop barking.It works on the rotties and border collies, but not so much on the little yappers across the street (I think they are pocket dogs).
