Stun Master stun guns have withstood the test of time which cannot be said for most of the stun guns on the market today. Stun Master is one of the most trusted and reliable stun guns on the market. Stun Master stun guns are simple to use and reliable. They are effective because of the low amperage shock they give. People usually think it is the high voltage of stun guns that stops an attacker. Not true. Voltage doesn't hurt anyone...it's amperage. One amp will kill someone. Our stun guns only have between 5-8 milliamps. Just enough to incapacitate an attacker without doing any permanent damage. They are Non-Lethal. You shouldn't worry about being shocked should the attacker be touching you. Won't happen! The current will not pass to you. Stun Master Stun Guns use high voltage and low amperage to temporarily disable an attacker for several minutes. The stun gun does not rely on pain for results. The energy stored in the gun is dumped into the attacker's muscles causing them to do a great deal of work rapidly. This work cycle instantly depletes the attacker's blood sugar by converting it to lactic acid. In short, he is unable to function properly. The Stun Master stun gun also interrupts the tiny neurological impulses that control and direct voluntary muscle movement. When the attacker's neuromuscular system is overwhelmed and controlled by the stun gun he loses his balance. Should the attacker be touching you, the current from the Stun Master stun gun will NOT pass to your body!
