Romaniac, Just stopped by to say the 18650 and the 14500 units i got back in June 2011 are still going strong with everyday use. These have the old switch and did have a sticking switch but a touch of baby oil and a quick thumb nail flick to each corrected the switch problem.
I love these PV's.
Do you have switch covers for these?
I'm going to be doing some hiking in Central America and would like to just carry them in some cargo pockets.
