I'd like to commend you on how tough your little flashlights are. My Stylus Pro either saved me from serious injury, or possibly, something worse. I keep my Stylus in my left breast pocket. Another technician was pressing an axle bearing on a 20 ton press when the press tool he was using shattered. A 7 oz. piece of the shrapnel shot across the space between us and hit me in the breast pocket with enough force to knock me to the ground.
It broke my light and bruised me severely, but I shudder to think what might have happened had it not been there. The little light continued to work until the battery died. Because the tube is crushed, I can't get the old battery out. I've got its replacement ordered and I plan to keep the original as a reminder of how fortunate I am.
