I would like to thanked my friend who advised me to buy self defense products for my own security. This is because one night our neighbor saw someone who was trying to enter in our backdoor. Since he notice that the guy taking too long to open the door, he guessed that it was a thief. So what he did is he get his flashlight and lights on the face of that guy. And he runs fast as he said. He is really a thieft. This is how he advised me to buy self defense products for security.
