Versatility and Compact wonder tool

I've used it several times

first this light is tiny. mounted, it's not an eye sore no matter where/how it's on the bike. I wish it was a little brighter, but 20 lumens is surprisingly bright the way these COB LEDs are configured. integrated charging mount means no messing with cables, a big plus. the magnetic mount is surprisingly strong. I've only used it on Road rides but it's never fallen off. the best part about the light for me is it can be mounted in a number of ways on the bike, or simply clipped to a seatbag or jersey pocket. my only caveat is that included mount isn't angled for consideration of seat post angle mounting and if the included mount is used, the light may be angled downward. my solution to that was using zip ties to fix the light magnetic mount to my seat post head directly under my seat and angling the light upward slightly.
