Best, brightest, safest light

I've used this as my rear visibility light for over two years now. It is unbelievably bright and has the unique advantage of being visible from the sides as well. I still haven't come across a product that competes. I use this to commute in dangerous road conditions at night, and the passing cars always stay nice and far away! There's a great full brightness, low frequency blink setting-- it can still last for hours at this setting even though it is very, very bright. Awesome customer service from Knog also!!!

Bright and multi-angled

I really like this light. It’s very bright and allows motorists from the side to see you as well. Its crescent shape fits my seat post perfectly. My only gripe is the lack of a “fully charged” indicator.

Hey Andrew, when charging, the light around the button should turn green when fully charged. See 1 min, 25 sec in this User Guide video - https://www.youtube.com/watch?v=BuXEPnr8oVI.

2nd Cobber is Great so Far

This is my 2nd mid-size Cobber. I love the brightness and the wide angle. I feel safely seen. Unfortunately my first one had its charging prong break in the USB cord. My second Cobber is working well so far and I am taking care in plugging it in.
