Advertised as the weapon of the future, this handheld device is capable of emitting intense ultrasonic blasts capable of inducing intense pain and discomfort in humans and animals. It's a great device to ward off intruders in your home, and it will be an even greater device when they make it purse size. It takes about an hour for effects of the devestator to subside and it's good to know it does not cause any permanent harm or damage.
A larger unit called the Sonic Devestator Riot Control, is also available. I like the way they say it produces an "irritation". Sure.
