Sadly the world is not always a nice place so people need to protect themselves, be it some punks or zombies. If you live in a country that doesn’t allow you to carry a gun (or you don’t want it) then this is one of the better ways. This knuckle blaster stun gun will hit attacked with 950,000 Volts (powered by only 2 included Lithium batteries), enough to stun them and give you the time to run away. Stun them for few seconds and your attacked will be disoriented, even fall to their knees. Be careful, it is not a toy so don’t accidentally zap yourself, let alone you private parts! No, you may not use it as an alternative way to vasectomy!
