Well never mend then. I will keep on bothering them
You question is a good one. I got trapped by a thunderstorm one afternoon this season five miles up a canyon on the Manti and had to walk out in the rain and dark on a trail that sidehilled 20 to 30 foot drops and one bad step would have been very hurtfull. One cheap flashlight keep flickering off, one regular bulb flashlight burned up the batteries and the LED head lamp batteries began wearing low.
Better quality flashlights is an item on my "gear improvement" list.
