Familiarity: I've put it through the wringer
Battery lasts several rides. Best if you use an Edge computer, easy to pair and makes it a one time function to turn it on. Once paired, you don't have to do anything except charge and attach it to the mount before the ride. Very bright, certainly bright enough to be seen as well as to see. Pulse feature for day time works great. Light weight, very much unlike their previous model. Recommend it without hesitation. Won't be being a new light for any reason that I can see.
