This mini stun gun has a rubber grip coating and a safety kill switch feature. There is a super-powerful LED flashlight included. There are two modes: safety and armed. The red light is illuminated when the stun gun is armed and one press of the black button will fire the stun gun. The kill switch is there to ensure that no attacker takes the stun gun. This is because when the kill switch leaves the stun gun, the Quantum will not fire. This makes the stun gun useless for anyone except for the rightful owner and more secure.
