Broke after 6 weeks

The mount did not line up with the holes in my rack, so with the undo stress on the mount it split horizontally and the light went bouncing down the road (fortunately it survived). Obviously, the mounting hole patterns are not standardized. I ride 100+ miles a week, and have been in single digit temperatures, so that didn't help it either. I ordered another one, and will shave down the mounting post that doesn't fit in the hole of my rack. The light clips to the mount perfectly, as you would expect. Hope this helps.
