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 type of success for so many years in a competitive field is the finest recommendation any product could be given. Stun Master stun guns are simple to use and reliable. They are effective because of the low amperage shock they give. People usually think it is the high voltage of stun guns that stops an attacker. Not true. Voltage doesn't hurt anyone...it's amperage. One amp will kill someone. Our stun guns only have between 5-8 milliamps. Just enough to incapacitate an attacker without doing any permanent damage. They are Non-Lethal. You shouldn't worry about being shocked should the attacker be touching you. Won't happen! The current will not pass to you. All Stun Master models have safety switches (except Stun Batons) and wrist straps. Stun Masters shown above use two 9-volt Energizer Eveready Alkaline batteries (except 100,000 volt which uses one). 100,000 Volts stun gun 6 " Tall Safety Switch Wrist Strap The Stun Master has a Lifetime Warranty.
