Appears to be well made with sharp hard ends on the hammer end. Small enough to fit on the center console but hopefully powerful enough to smash the side window. I hope I never have to find out, but after witnessing the rollover and nobody (5-6 cars pulled over to help) had nothing but a crowbar to throw out the window and a not sharp pocket knife to use Cutting seat belts, I decided to buy one each for my wife, daughters and myself. It was a "panic buy" but justified in my opinion.
