Familiarity: I've put it through the wringer
I got this headlamp at the beginning of last summer (I work for an adventure camp for summer break), I needed something I could trust to take some beatings and hard use, this was it. It was always in my pack.
I was very impressed by the brightness controls, and love the red light feature (great for night/milkyway photography). However, be advised that if you are using it for 10-15 hours a week you will probably notice the power drop by the end of the week (it eats batteries for breakfast).
If you need a headlamp, go for it. You won't regret it
