Stun guns have been proven to stop an attacker by attacking the nervous system. Now there is a more advanced technology that is being applied by the M-18 taser.

This is the EMD or electro-muscular disruption technology. It releases a powerful 18- to 26-watt electric signal that can directly control the muscles. The attacker is left helpless as his muscles become uncontrollable and he falls into the ground in a fetus position.
