Awesome lights. Lots of options and all are very bright. Really good battery life & easy to charge via USB port.
I had it attached to my underseat storage bag and it fell off on the first ride never to be seen again! It appeared to be very good and bright but I'm incredibly disappointed to have lost it.
Great product, have purchased several rear and front lights now, very robust and easy to use
This is my second one because the battery life on the first one was !@#$. I like this light because of the brake lights coming on when I slow. Dislike is one of the flashing modes has a periodic very bright flash and the rider following complains about it. An improvement would be a flash mode with an irregular pattern and without the peloton eye dazzler.
