High visibility, easy to recharge
by Anonymous

I really enjoy the visibility of this light - 300 degrees is hard to beat. No longer can people say they didn�t see you because they were not right behind you. Great choice of modes and easy on/off. Even better is the lack of a cord. Just plug it into a USB socket. Done. Great longevity as well.

very bright but hard to attach
by middle age triathlete

I ride mostly urban roads with lot of traffic during afternoon/ evening hours.

I love the high lumen visibility and the different blink patterns.

Attachment to the quick release mount is very finicky. Surely a better solution can be had!

Fantastic Light, Not Durable

Worked terrifically for 1-2 months of dry use. Once Fall rolled in and I went out on a rainy century it was totally unusable. Would not turn off. Then the small on/off button fell off (looks like it was held on only be an adhesive? Also noticed water has seeped into the light and some odd liquid has seeped out and dried. Again, I assume some sort of adhesive? It could not stand up to one long rainy ride, but worked really well for my commutes and rides up to that point.

Customizable light with safe vaibility
by Johan
6 of 6 customers found this review helpful.

The light is very visible all around and a bit too bright. Too bad unable to customize brightness but only the blink pattern with the app.

The medium size is a bit bigger then I imagine
