Dustin Ellermann posted this test on the flashlight from 300 feet... "Ultimate torture test of the Elzetta Flashlight (don't try this with Chinese made junk). Dropping it twice out of a helicopter, once into hard North Texas dirt and again onto concrete. The only thing that failed was the batteries, I changed them around and the light still works flawless. I'm proud to have a few scratches on my personalized flashlight knowing what it can handle."
