I love this light. Visible and long battery life
Great clip on light. Bright, with nice flash-pattern options. My only nitpick is that it can be fiddly to actuate the on/off button while mounted to the seat post.
The best bike rear light to Brightness and good quality . I think anyone can see from far away..
I haven't used bike lights before and found this light brighter than expected, which is a good thing. I dislike riding behind bikes with blinding flash modes, but the fading flash and alternating flash modes are helpful in calling attention to yourself without irritating people behind you.
Just bought my second Knog light. The only reason is I lost the previous one on a ride. Highly recommend!
