A stun gun is a legal electrical self-defense device that puts out a high voltage and low amperage shock. To put things in perspective, one amp will kill a person. Our stun guns deliver 3 to 4 milliamps. This is far below the amperage that could do any lasting damage to an individual.
By merely touching a person with the stun gun for a few seconds, he can immobilized for several minutes with no permanent harm. Stun guns are considered reasonable force to resist attack. They can be used many times to ward off attackers before the battery needs recharging, or replacing.
