my dad bought me one. This gas spray is very effective. if you spray straight to one's face/eyes, he'll giddy then collapse! Even people around(forgot how many metres away) also will being affected like tears keep on forming, giddy. but make sure you run away after you spray or else you'll kena also =)

btw, it's quite expensive which cost rm500 for 5 times spray. means everytime you spray rm100 will gone. =P

the brand is call My Keeper. and you need to apply a license for that. So in case somebody wanna sue you for that,just show them the license. ^^

should put it in your pocket everytime you going out.... perhaps standby if you doubting someone..
