Good luminosity, but what's it for if it can't be installed?
The clamping rubber strap was already sticky out of the box, the rubber had already degraded, when installed on the seatpost with just a slight pull it broke immediately.
After it broke, I tried placing it on the thinner rear fork tube, but again the rubber broke.
It went in the trash.
