Features: *Worlds Smallest Stun Gun *Safety Switch *Free Holster *Lifetime Warranty The ground breaking design of the Streetwise Small Fry Stun Gun enables 400,000 volts to fire out of a stun gun that is so small it can actually be concealed inside a pack of cigarettes! Traditionally, the higher the voltage of a stun gun the larger the unit had to be. This is because they are normally powered by 9 volt batteries and the higher voltage units required three or four batteries. By using 3 volt lithium batteries, which are powerful batteries but are only 1.25 inches tall the Small Fry has revolutionized the stun gun industry. Now you do not have to choose between a small stun gun that is easy to carry and conceal or a high-voltage unit that is large and bulky. It easily fits in the palm of your hand or can be concealed inside a pack of cigarettes. For those who would prefer to carry it in a holster we have included in a small heavy-duty nylon holster with belt loop. Requires three 3 volt lithium batteries. Small in Size, not Stopping Power: When an attacker is touched by the Small Fry it will disrupt the message the brain sends to the voluntary muscles. Simply touching an attacker 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. Safety Switch: to prevent accidental discharge, the safety switch must be in the "on" position before the unit will operate. A red light will illuminate above the safety switch to warn you that the stun gun is ready to fire. Holster Included: includes a heavy duty holster with belt loop for easy carrying. Lifetime Warranty: the Small Fry Stun Gun is one of the highest quality models available and comes with a lifetime warranty.
