Security in the palm of your hand keeps getting better and smaller. They call this the Streetwise SMART Keychain stun gun since it is the first one to replace the traditional safety switch with a Touch Sensing Safety. When feeling threatened or frightened we sometimes don't think as clear so why run the risk of forgetting to turn off the safety. This time saving innovation senses when the unit is in your hand in the “stun ready” position and automatically turns off the safety.
The patent-pending design also has some features others stun guns don't. These include battery status indicator lights to easily know if you have a full charge and the ability to use the stun feature while the light is on (other models require you to change from flashlight mode to stun mode). This saves more valuable time when you need to quickly defend yourself
