The hammer is a great product, but the installation is bogus. First, the recommended velcro doesn't work because there isn't enough surface area on the back for any velcro to attach, and, in fact, parts of the back are concave which makes the velcro impossible. There are, however, holes for a screw installation. I was able to remove my center console and attach it with three screws, without any damage to any electrical system in the car. Now that it's attached, I'm happy, but the directions were a little lame with regard to installation. Otherwise, 4 stars!

I hope I never need this item. However, I am glad I have it. I bought it because I saw it reviewed on television and decided it was worth it to have this item on hand.

We have three of these handy little devices. Hopefully we will never ever have to use one of them, but it gives some peace of mind having them available. When we received our first one (we only bought one to start with), we took it to a local junk yard (they guy who owns it likes my friend and me) and he let us test it on several trashed out cars. The hammer works perfectly and can take a side or rear window out in a flash and the cutting end works great on seatbelts. Actually, it was sort of fun breaking out windows, something I have not done in years. Anyway, it worked well, so we bought one for both my cars and my friend bought one for hers. I would buy one for my sister, but she would spend twenty minutes trying to figure out which end to use on the window, and by then it would probably be too late. This is one of those things you hope you will never need, but if you do need it, it is sure nice to know it is there and that it actually works.

I wanted to have something in my car if I had to break a window so I decided to buy lifehammer. It is made very well. I hope that I don't ever have to use it.

I hope never to use this product, but it is good to have in a state with a lot of lakes, ponds and bogs around twisting country roads and no street lights. Product fits nicely in door pocket, is sturdy and light weight. Handle grips well and would be easy to use in an emergency.
