First, we revolutionized the stun industry by introducing the original Streetwise S.M.A.C.K. (Stun My Attacker Compact Keychain) Stun . This amazing stun device was about half the size of stun guns on the market at that time and was light enough to be carried on a key chain. We followed that with the Mini S.M.A.C.K. 20,000,000 which was similar in size to a small pack of gum, making it the smallest keychain stun in the world! In our never-ending pursuit to build the perfect mini keychain stun we are proud to introduce the USB Secure 22,000,000 Keychain Stun Flashlight, the next level in full-powered small-scale stun guns. We have improved on the design and function of our keychain stun . Now the white button in the center of unit activates the stun and when you need a temporary light source you simply slide the switch upward. Although this unit does not function as a USB storage device, you are the only one who will know that. When attached to your keychain the bad guys will have no idea what you are â€œpackinâ€ until it is too late! Simple operation, compact size, discrete design, and a mighty stun make the USB Secure by Streetwise Security Products the obvious choice for those who want the next generation key chain stun !
