Ownership Update 3/31/2010
After being drenched in a torrential downpour the lowest "red" light setting started flickering a little bit. A finger tap or two and it was fine and there were no issues with any of the other "red" or "green" settings but it appears some water penetrated someplace in there and affected contact a little bit.
After a day the issue ceased (I'm guessing the water dried out).
