Stun Master has been a leading brand in the stun gun industry since 1994 making it a true icon in the world of self-defense.  This Stun Master has a safety switch and wrist strap.  It uses one 9-volt Energizer Eveready Alkaline battery.  The Stun Master has a Lifetime Warraanty.

Stun guns use high voltage and low amperage to temporarily disable an attacker for several minutes.  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.
