A 7-in-1 Emergency Tool, this Swiss+Tech emergency device hangs from your key-chain and can save your life with its glass breaker, a seat belt cutter, sonic alarm, bright LED flashlight with both a high beam and low beam and an emergency flasher. If the safety features were not enough, the BodyGard offers a digital tire pressure gauge and a thermometer. The glass hammer requires no force of strength as it has a built-in spring-loaded mechanism. The sonic alarm has a high decibel output. Carrying the device gives you peace of mind that in the event that you need to break out of a car because of an accident, fire or water submersion, you can do so by cutting your seat belt and breaking the window glass.
