I set this up to discourage my neighbors dogs from coming to their fence and barking non-stop whenever I go out into the yard. The unit was set up just 20' from the dogs (across a narrow dirt driveway). Although I verified it was working, it had no effect on the dogs. I'm giving it a 2 instead of a 1 just because "I don't like it" sounds better than "I hate it". There's just really no answer to a neighbor's barking dogs if the neighbor just doesn't care. Maybe a Super-duper Bark Stop powered by 120 volts with about 10 times the output might do the trick.
