On the bike this light works well--bright and compact. However, I question the running time claimed by the manufacturer. I get about 10 hours. I also am quite frustrated by how much time it takes to recharge the thing. Without its battery being fully drained, in my experience it takes in excess of 48 hours of plug-in time to get the elusive green light. Seriously. I have contacted the manufacturer about that, only to be told that, yeah, it takes that long. So if you have the patience to wait, and not the need for the light for a couple days, I guess it's a pretty good product.
The lights themselves are great, nice and bright with different settings/blink patterns to match the conditions! The main problem is the strap for the rear light, it's flimsy and does not have one side permanently fixed to the body of the light. Within a week of buying two light sets, one rear strap broke and the other was lost while off the bike being charged. Lezyne sells replacement straps for ~$5, including different lengths, so I bought multiple.
I keep losing lights that have all kinds of creative attach methods at to the bike. I was looking for a rechargeable, bright USB-C chargee light that. Thats exactly what it is. So the light is attached to the rubber strap and cannot fall off. You need to remove the light with the rubber strap to charge it. Not as nice as having it clip in but really nice that it can't fall off.
Only complaint is that the rubber strap could be a bit longer. My gravel bike has a mountain bike width seat post and the strap is a bit tight on that.
I commute in Seattle a couple days a week year around and bought this 15 months ago with the hope of being able to take the round-about way home when its not raining. However, the battery life even on the 100 lumen economy mode was just over 3 hours instead of the 10 hours advertised when new and now it's down to closer to 2 hours so I need to pack my old headlight as a backup if I want to get in some extra miles. When I do need the full power on unlit gravel trails, it does a great job lighting things up but that kills the battery very quickly. If you don't mind charging often, it's a fine light but don't expect to be out too long after dark.
