Query: Mine didn't last.

I've owned eight Streamlight flashlights and only one still functions. My original Scorpion is still going strong after years of use as a Peace Officer. My Key-Mate quit after just a few months of intermittent use. Five of the eight Streamlights used LED's and the electronic guts in them just didn't last. Don't think I'll ever buy another Streamlight LED flashlight ever again.
