The VIPERTEK VTS-881 micro stun weapon really packs a punch! Simply test shooting this system into the air is frequently enough to stop an enemy. As the intense electric current pulsates in between the test prongs and creates an intimidating electrical noise, an enemy with any sense at all will be stopped in his tracks. If the sight and noise doesn’t stop him, a shock from this stun weapon definitely will bring an assaulter down! When an attacker is touched by the stun gun it will interrupt the message the brain sends to the voluntary muscles. Merely touching an aggressor will deliver a high voltage shock triggering loss of balance and muscle control, confusion, and disorientation bringing him to his knees and making him incapable of additional aggressive activity.
