Familiarity: I've put it through the wringer
Love the light for the no button swipe, and the white light usage. However, the crenelated surface used to diffuse the white causes the red LED to have multi-point dim light sources on the ground. Not safe nor bright enough for night time forays to the Groover in the Grand Canyon. Sure wish it worked better. Might have to modify the lens and polish it clear.
