Review on Enhanced Swiss+Tech ST81005 Black 5-in-1 BodyGuard: Auto Emergency Escape Tool with Panic Alarm and Flasher by Chris Willis

Video and product description are correct. It's also more durable than a cheap small keychain. The beeper is loud enough to have people looking your way if an intruder is crawling around a family member and hasn't yet smashed the window with a trusted blade. I have used similar ones in my job as a police officer and they will smash the window. I bought one each for my wife and daughter. It's better than nothing for peace of mind.
