Have used one in several different camps last 3 or 4 years. The primary uses are to keep bears away from the airplane or the meat cache. We store all of our personal food stuff behind the wire too. Have not had the bad experience of finding a shreaded plane or lost any meat. There is no doubt that they will kick your pants if you come in contact with them whilst they are working...
I cannot say that I have witnessed a bear getting hit by one. Lots of proof that bears are as common as rabbits in most places I hunt though
