very durable unit, very comfortable, lightweight due to the size of battery used. The only issue I have with it is the switch on top. It is hard to move into on/off position. I do like that there are very few moveable parts, less things to break.
Switch does not seem to engage fully at times, producing flickering light. Useful battery life is not 140 hours as claimed with new alkalines or NiMH's, it is more like 40 hours.
