Great light with visibility from side angles
by WATriker

I use this light on the flag mast of my recumbent trike. Since the recumbent is quite low relative to vehicle traffic, increasing visibility in terms of both height and side angles is especially important. The Big Cobber allows me to do both.

It's only downside is that in order to connect the charging cable, the attachment bracket must be removed from the light each time.

Only works for about a year

I bought two of these lights. They were very bright and easy to use so I got a couple more. Two of them died in a rainstorm. The other 2 just stopped working after about a year. I have the Knog Mob blinder lights as well, no problems with that model

Does not hold charge and light has short life. Overpriced
by AZ ROADRIDER

Have used this light for less than 6 months riding in southwest. The charge lasts less than an hour even after following manufacturers instructions. Light no longer works even after full charge. This is poorly made overpriced product that I regret buying

Outstanding Light

First, this light is huge, and can seen from the back and sides. I love the attachment mechanism - it stays in place and is easy to mount and un-mount. I have owned a number of Knog lights over the years and this is on par with those. Put another way, if you like other Knog lights you'll probably like this one as well. It's a little pricey, but can you really put a price on being seen? Worth every penny in my opinion.

Bight Light. Highly Effective.
by Anonymous

I give this light a split star rating. Five stars for the light itself. The light is very bright and well seen from the side and rear. I gave it a four star rating due to the attachment system which is a rubber band. I would prefer a clamp, but it has not been a problem on the gravel roads I travel. Easily charged with the supplied cord or a direct plug into a USB port.

NOT waterproof!
by Carol

Im on my second one of these since October and now its about to go back. Fits my aero seat post, is Fantastically cool looking and bright but as soon as you hit a little rain, game over. Works again after it dries out but battery life is tremendously shortened. So disappointed.

Best rear light!

This is the absolute best light for an aero bike. Get a decent 5-6 hours out of a charge using the mode that slowly flashes around the whole light radius.
