A stun gun is a self defense device which disrupts the message the brain sends to the voluntary muscles. Simply touching an attacker with a stun gun 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. Streetwise brand stun guns have more features than any other stun gun on the market. The built-in 130 dB ALARM offers you two levels of protection: At the first sign of danger you can activate an ear piercing alarm to scare off a potential attacker and summon help. If the alarm sound is not enough to deter the attacker, the stun gun may be used. A STRAP worn around your wrist attaches to a DISABLE PIN on the bottom of the unit. If this stun gun is taken away from you, the disable pin will pull out and prevents an attacker from using it on you. The SAFETY SWITCH prevents accidental discharge. The disable pin must be inserted, the safety switch must be in the "on" position, and the trigger pressed down before the stun gun will operate. This unit is small enough to carry in your pocket. With the free holster, it can be clipped to your belt or purse. Requires one 9 volt battery.
