Familiarity: I've put it through the wringer
This has become my go-to headlamp for 90% of my activities. First it weighs 1oz. I have no excuse to not throw it in my daypack, bike, or touring pack. It is the size of an emergency light but performs at a comparable level to a modern full-sized headlamp, all be it for a shorter duration. The light is bright enough for trail running, is comfortable and does not move on the head, is rechargeable and waterproof. I would bring this light on a thru-hike, and I use it for all of my overnight trips. Polite red mode is a nice touch on such a small light, for use in the tent. Unless you are out at night for a prolonged period of time, or engaging in active route finding this light is more than adequate for the job. I've had mine for four months now of frequent use and it has held up great, still holds a charge as if it were new, and has even survived a couple of downpours. I ran it out of battery once on a long night hike, but was still able to make it down using the emergency mode. The only downside is it is hard to find because it is so small!
