I bought one of these for each of my family. They are great just in case you ever have an emergency and need them. They have a glass breaker, seat belt cutter, flash light and compass. I recommend getting one for everyone in your family who drives a car.
I need to buy more so I have one for each car in the family.
This is just one more gadget in my arsenal to help give myself some peace of mind and be ready to take care of my family in the road. Great quality like the other items I have purchased from C Larboard.
