A well made tool.

mglotustvrDecember 24, 2025

Don’t exactly want to have the experience of having to use the Safehammer but it is well made and worked extremely well on the glass samples included. The ‘O’ rings on the end caps are a little too tight for my older hands so I put a drop of 3 in 1 light oil on the ‘O’ rings. Perfect result. Read more

Good glass breaker; requires training and backing glue not strong enough

RonSeptember 18, 2025

While the lids on both sides appear to be hard to open, I installed the rubber grip pads ans gave these to my 11 and 8 year old children and both managed to open them without too much issue. The rubber grip pads do slide around and can be taken off easily, which is worrysome, as the backing glue lacks strength. Because of this, I have yet to install inside my cars until I get a strong glue tape. In terms of the actual function, the glass breaker works flawlessly, but it does require some training, and it requires a good amount of force to engage (especially with young children who struggle with pointing it perpendicular to the glass as they press).

Great gift for young drivers and old ones

Sweetsmiley00December 29, 2025

I bought these for my 4 kids and husband for Christmas. (Gotta ensure everyone is safe ;D ) The hammers come 3 in a pack. So I bought two packs. The varying colors were great! It allowed everyone to pick the color they wanted. The 3 pack comes with them snuggly fit in a plastic container, inside a cardboard box to prevent damage. The plastic holder contained 3 hammers, a sticker sheet containing finger grips to place on the hammer where you would like (plenty of extra grips too), and three clear disks. The clear disks are for practicing the spring loaded hammer. Two of my kids were VERY eager to give it a shot! - FYI you'll need to have it contained in a box or taken somewhere that's NOT the livingroom floor. As the glass shatters into pieces! Please be more careful than my kids were... These hammers are lightweight. One side pops off for the hammer. The other end pops off for the seatbelt cutter. Which is exactly what I wanted. To ensure if ever needed, they can escape an accident. They found them easy to get out of the package. Easy to pop ends off and easy to use. Which is a little peace of mind for this mom! I think price wise, its super affordable! And I'm very glad I purchased them. It's a gift that if they never need to use it, we're super lucky! But if they need to, they have the spring loaded hammer. Which is really good, as the spring loaded hammer will continue to work even under water. I had read a study that the spring loaded was more effective at breaking glass than the hand held hammers, numerous times. (Plus, if you're under water, how are you going to swing with enough force to break it? You can't) Definitely recommend these little guys. Just stick it in your car. Near the driver seat so you always have access in an emergency. In water or on land. Thank you for giving this mom a little rest at Christmas! Read more

Great gift

NoelleJanuary 2, 2026

Living in FL with a lot of waterways, I thought this would make a great gift for my family. I like that it can be mounted in the car for easy access and that it is small. I love that it comes with a sample glass piece to be able to try it out- and it definitely works well! Read more
