Familiarity: I've put it through the wringer
I bought this to have a higher upper limit on brightness when climbing at night, and this fits the bill perfectly! At full blast this thing makes night climbing no problem. I also use it to have better route finding at night, be it on the cliff, trail, approach, etc.
