Its a powerful 4.5 Million volt stun gun. This stun gun will really give you the edge since an attacker will think you are just carrying a cell phone. It also has a very bright built-in 6 LED flashlight. All PRETENDER Stun Guns come with a LIFETIME WARRANTY and FREE Holster. To prevent accidental discharge, two levels of safety have been built in. The safety switch must be in the on position (this will cause an LED warning light to come on) and the trigger button pressed before the unit will operate. The rechargeable model comes with a built-in rechargeable battery and an easy to use integrated charger. Simply plug the charger into the stun gun and then into an electrical outlet. Free holster also included. Note: None of these Products works as a Cell Phone – Only as a Stun Gun and Flashlight.
