This is not a knock on the light itself, but this light was a bit bigger than I expected when it arrived. It would be nice to get pictures showing approximate size compared to something common. As for the light, it works well. The adjustable attachment system worked well on my handlebars and holds the light very securely. The quick detach is nice so that I can take it off easily when I lock my bike up somewhere. The two light modes aren't incredibly different, but it is nice to save some battery life when I don't need a bright light.
