If you have suburban neighbors with barking dogs, you'll want this product. I place it near the top of the fence where the neighbor can't see it, and it sends an irritating, high-frequency signal out when the offending dogs bark. It doesn't work 100% of the time, but boy has it made a difference! The dogs used to bark for hours when the neighbor wasn't there, but now the dogs are usually either quiet or will whine for a while and stop. Uses one 9v battery, which needs to be changed around every 3 weeks with heavy use. Change the battery when the "egg-trained" dogs start barking again. Range is 50 feet. 4 stars.
