Being an owner of many cars in my garage i was looking for a safety device exactly like this because my friend encountered a situation where he needed this. I am writing this on behalf of him to show the importance of this tool! Many car owners skimp on simple safety tools which should be present in every car. Remember your life is more important than anything else. So wear your seatbelt and stay under the speed limit always and drive cautiously! So this tool is lifesaver. Suppose you are involved in a bad accident (hope that never happens) and your car rolls over and is badly damaged or mostly if your car caught fire 🔥 then the car's electrical system stops working and the door do not work so then you can break the glass with the help of this tool. You can also cut the seatbelt incase the mechanism is stuck which is most important! TIP: You can also use your cars headrest to help you escape. Remember that it is only an emergency tool and not to be used for any purpose. Hopefully i could deliver my message to many viewers and please buy it as soon as possible!
