As a Certified Child Passenger Safety Technician I have been wanting one of these for a long time. The tire gauge part I use on my stroller since my husband prefers to use a standard one on our cars, but the rest of the features are perfect for an emergency. The glass breaker stores inside so if your kid grabs it they are not going to break your windshield in seconds before you can get to them. The seat-belt cutter is great for if you need to get out and have a jammed belt, also it is best to remove your kids inside their car-seats if possible to minimize spine and neck movement after an accident. If you have a jammed belt, or you need to be fast you can just cut right through them! Obviously the flashlight and red LED light are great for night-time emergencies, changing a tire, and finding your cell phone that went under the front seat..not because you dropped it while driving of course!! I am very happy with this product!
