1. Siren Song
This is inspired by the Military, it uses ear piercing sound to deter criminals and is rapidly becoming one of the most sought after safety devices in America. Every child and woman should have this device. The Siren Song isn’t just for protection, but can be used to saves lives by calling for help if you’re having a heart attack or have some other health condition, which prevents you from shouting for help. The keychain design is perfect for use with house keys or car keys. It can also be attached to a backpack or a purse.
