“Much better than the mount that came with the light – unless you’re moving your light between bikes regularly. But it holds the light in position much better.”
“Not very good. The mount that came with the light is much better. The thumb screw comes loose all the time. The light rattles in the mount because the fit is too loose. (Doesn't rattle on the original mount).”
“Its very good because it has several spacers which can be added / left out so that the clamp will work with various thicknesses of handlebar.
The tightening mechanism (a screw which you tighten with your fingers) works well. When tightened correctly, it is rock solid.
Its a bit chunky for those who care about such things.”
