The rechargeable Streetwise stun baton is a self defense device which disrupts the message the brain sends to the voluntary muscles. Simply touching an attacker with a stun baton for three to five seconds will deliver a high voltage shock causing loss of balance and muscle control, confusion, and disorientation bringing him to his knees and making him incapable of further aggressive activity. Full recovery takes about five to ten minutes and there is no permanent harm. Measures 18 in. long. Just test firing this unit into the air is often enough to stop an attacker. As the bright electric current pulsates between the test prongs and creates an intimidating electrical sound an attacker with any sense at all will be stopped in his tracks. If the sight and sound doesn't stop them a jolt from this unit certainly will! Holster Included: includes a heavy duty holster with belt loop for easy carrying. Life time warranty: Streetwise Stun batons are of the highest quality and come with a lifetime warranty. The current packaging for this product is a plain brown cardboard box.
