Bests & Worsts Reviews from Amazon

I'm a firefighter and I have used this tool many times on the job over the years and it works very nicely. There are a few points that should be explained to anyone buying this.... 1) If possible, wear a glove! you have to push this against the window with some force to activate it and it is easy for your hand to continue forward once it shatters. sometimes just a hole surrounded by cracked glass....it's sharp...it hurts. If you don't have gloves, make a conscious effort to not continue forward when the glass gives. 2) Side windows are tempered glass and windshields are laminated glass. This will work on a side window but not a windshield/rear windshield. Side windows "cube' and fall apart windshields do not because the plastic sheeting in them keeps the shards together. It is hard to kick a windshield out even after it has "spidered". 3) A good spot is usually near the corner (about 2"-3" diagonal from corner) and there's less chance of putting your hand through it at the corner....did I say that glass is sharp? And that it hurts? It is....and it does! 4) If you're getting someone out of a car and they're conscious...tell 'em to turn away when you break the window...cuz...you know...sharp...hurts... 5) Seat-belt cutters work way better if you can manage to pull the belt taught with your other hand. 6) If you have this hanging off a fire-coat...it is very likely it will fall off...break off...etc. I stick mine in the rubber flashlight band on my helmet. Not that I wanna tell you where to stick it or.......yeah....OK... 7) These don't work over and over forever. The point gets dull. But when I get a new one, In usually test fire it on a thick piece of cardboard or soft wood to make sure that it functions. 8) Just hold against window and push until it pops. That is all....stay safe...and remember... Glass is sharp....and it hurts!
