Window Breaker Seatbelt Cutter - 2 in 1 Portable Safety Hammer Glass Breaker for Car Emergency, Car Essentials, Automotive Escape Tool for Men and Women, 2 Pack, Red

We haven’t had to actually use these yet, but tested it on an a bigger piece of already broken glass and snapped just like it should. I’m glad to have these in our cars in case of emergency. Nice that it also has a seatbelt cutter. Great price for the quality

I had the old traditional hammer-style breaker but it was bulky and wanted something small for my WRX. I saw that this had bright red color with glow in the dark green stripe for better visibility and was surprised to see that there's a thick sample glass you can actually test it on. It works like a ratchet center punch where you push it down until it clicks. That force makes the punch make a dent even on a piece of aluminum which, of course, shatters any glass. I made a video and was quite surprised. I did it outside so it didn't go all over the floor inside the house. This mechanism seem faster than trying to swing a hammer to break the glass in an emergency! While I haven't tried the cutter, I did try to cut pieces of paper and seems to cut it butter smooth so I'm sure it'll be no issue if the belt ever needs to be cut.

I like these, have bought at least one for every car. Easy to use, and I love the practice piece of glass! Really shows how good it works. My biggest complaint is that the adhesive is not great. In one car the adhesive stuck to the car, but came off on the tool end! (Oh brother). Other cars, it didn't adhear well to the car dash. Dash was clean, smooth, no angles. I'll have to buy some kind of better adhesive.

We actually used it to break a pretty thick piece of glass, so we could box it up and throw it away safely. It worked even better than I expected!!!

Great gadget to have in car

Seems like it will do what it’s supposed to but it would help to have one glass piece to practice on per tool ordered. I ordered two 2-packs and it only comes with 1 glass disc per 2-pack. It would be good to be able to have a spouse and kids practice to know what it does.

3m adhesive doesnt work on my interior. part of the function is to be handy quickly in an accident. Defeats its purpose if you can't. install it within reach.

I love that these are smaller and can be added to a keychain. I keep similar tools in all my vehicles but when the time comes you need these seconds will save your life so I want it in the easiest place to get to. Everything seems good quality the ends don't even thread on to save time they push on and are held by o rings. Great compact design.

I was extremely pleased with this item for safety and peace of mind for my adult children. They travel on roads that follow a body of water through the mountains carrying a precious cargo - their children. This item allows me to do as much as possible to keep them safe. My only negative is the sticky piece that holds it on the dash does not hold very well and will have to find another solution.

Seems to work on the test glass well. I hope I never have to use it. A Glass breaker is something everyone should have, you never know when you may have to break a window to save a child, someone in medical distress, or a pet. Especially in a heat wave

I’m sure we have all seen the terrifying moment in action movies where someone is trapped in a car that has sunken in water or flipped upside down. It is very hard to push a car door open when it is held shut by water pressure or gravity. The obvious solution is to break a window to escape, but the tempered glass used in vehicles is very difficult to break. A window breaker tool uses a hardened steel point to crack the tempered glass allowing escape. This particular glass-breaking tool is unique because you simply remove the protective cover and push is against the glass, once you have pushed it hard enough, a strong spring fires the metal point into the glass. This is a better solution than the typical glass-breaking hammer, because it can be difficult to swing a hammer hard enough while under water or in a tight space. This emergency tool even comes with a small piece of tempered glass you can use to test it. This is an important safety device and I will be placing them in each of my family’s vehicles. I reduced my rating by one star because the seatbelt cutter is operated by pushing the blade onto the seatbelt - meaning that you must use two hands to make it work, one to hold the seatbelt fabric and another to push the blade through it. A one-handed solution where you use the blade by pulling not pushing would be much better.

I think this is mandatory for every driver. It did come with a piece of glass and I tried the glass breaker. It shred it into pieces. It's a small price to pay for your safety. I gave one to my daughter too who is a new driver. Brings me peace of mind to know she has one.

Small but mighty. I like that the include a sample of glass to break. Wear glasses.
