I know it has been two years since this thread was last responded to but I feel I should respond to it now that I have had these flashlights for, well, two years.
I would not buy this flashlight again if given the chance. Both flashlights have broken at least twice, specifically the battery holder. Both have had the top button break off. I glued it back down but they broke again. This time to fix it I drilled out the holes and epoxied in metal brads and then epoxied the top button down again. This has held so far. The latest was the "legs" on the battery holder. Two of them have broken. The epoxy is drying as I type this out.
I have not been rough with them, never dropped them or mishandled them, but the next time I consider a new flashlight, it will not be an Element K2 for $15. It will be something much more durable.
