I was wondering something about my CMG and possibly other lights that you turn on by twisting. When twisting by tightening to turn on, is it possible to keep twisting to far and breaking the little circuit board? I only twist until if turns on, but I worry about people who say "can I borrow your flashlight?" and then decide they want to twist more to see if it gets brighter or some silly thing like that. Would it be best to carry my solitaire as a loaner or am I just worrying over nothing? Thanks.
