ResQMe is a unique, portable, reusable safety device that goes on your keychain. This innovative tool allows people to escape from being trapped in vehicles. To use ResQMe, pull the clip away from the product to reveal the cutter, then hook over seatbelt and pull. To activate the window breaker, simply push the black head against a side window until the concealed springloaded spike releases and shatters the glass. ResQMe is made in the USA and carries a 5-year warranty.
