Familiarity: I've put it through the wringer
I have gone through far too many other headlamps before finally finding this miracle. I enjoy the different brightness options. Its brightest setting can turn anything into daytime but does burn through battery at a considerable rate. If you run this at its lowest setting it will run for days before it needs a recharge. The battery is long lasting and charges quickly. I charge it in my car on long camping trips using my car adapter.
