Familiarity: I've used it once or twice and have initial impressions
I did a midnight ride with 3,000 of my closest friends. My light was one of the brightest on the road, and I only put it on low power to conserve the battery. I rode for 3 hours and the battery held up great. It is super light weight and convenient. I would highly recommend this light.
