There are a lot of useful gadgets in this world. However, there are some that you hope you never have to use. These devices are usually ones needed in the event of a life-threatening emergency. Take, for instance, this ResQMe.
If you are ever trapped in a car that is submerged in water, you’d be surprised at just how difficult it is to get yourself out. Not only do you have to get out of the seat belt (which could be jammed as a result of a crash) but you also need to break out a window so you can swim to safety. This little keychain helps you do both. Just pull it out of its clip, pull the seatbelt through it, and use the little punch on your window. The punch is spring-loaded, so it can create enough force to shatter a car window. For $10, I’d say this is something good to keep in your car, just in case.
