This is the brand new, 3.5 million volt rechargeable stun weapon from STUN MASTER. This stun gun's small, compact and ultra slim design is great for people with small hands. The convenient, side mounted safety switch alows you to chose three selectable modes of operation; stun only, flashlight only and off. The integrated Ni-Cad battery makes this unit convenient as well as powerful. Just plug the included charger into the gun and then plug it in the wall. The built in charge indicator lets you know when you are ready to rock!
