The Stun Master 100s uses high voltage and low amperage to temporarily disable an attacker for several minutes. The self defense stun gun does not rely on pain for results. The energy stored in the safety device gun is dumped into the attacker’s muscles causing them to do a great deal of work rapidly. This rapidly working self defense cycle instantly depletes the attacker’s blood sugar by converting it to lactic acid. In short, he is unable to produce energy for his muscles, and his body is unable to function properly. The 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 will NOT pass to your body!
