I've got a couple of these and they do what they are supposed to. No trouble with the switch. The directions tell you you must press the switch twice to turn the light on. The low power setting is plenty bright for digging around in your tent. High is adequate for running in the dark. the 2 red lights' beams are centered about 10 inches apart at reading distance, for me about 18 inches from my eyes. This seems adequate but I don't read with the light. I mainly use it jogging in the early morning. The flashing red light is good for this when on busier roads and the high setting is great on a dark trail. The light does not bounce around and it uses one AA battery, about the most ubiquitous battery there is. No complaints.
