Sorry, switch rant follows...
Unreliable flashlight switches do really bug me, especially as there are such things as reliable, i.e. proven half million cycle +, industrial switches available, and for only like $5 or so. I would be willing to pay extra to at least have the option of a heavy duty switch put into a "heavy duty" flashlight.
I may be unique, but I've only had bad luck with my 2 plastic bodied Krolls. The metal Streamlight SL Kroll worked better for me, but I gave it away before I used it that much.
Excluding Surefires (I'm too cheap for them), the only manufacturer I know of who claimed to use a real industrial quality switch is Infiniton for their C1, which I have one of. I haven't used my Infiniton C1 that much, but I like the idea that there is a real industrial switch in that thing.
Otherwise, the only thing I trust is the old arc style twisty switch with just a pusher post in the tail cap. I use my other lights of course, but I always remember that a tank tough $40 light still depends on what is probably a 25 cent plastic pushbutton switch...
