Everyone who has complained about the bolt being too short must have had an impact on L&M because the kit I received had a bolt that was indeed long enough to thread completely into the light. I have been using this mount on a KOM cycling computer/gopro handlebar mount on gravel and road and it has not come loose at all.

Like the other reviewer, the screw is obviously too short to be useable.

Waiting for L&M’s response from a support ticket at the moment.

The light floats up and down with zero resistance. The diameter of the hole is too large and the mating surfaces are loose and frictionless. Useless. Needs a redesign that actually works. Sad.

Cheap plastic gave up after breaking two. Needs to be metal

As below screw too short.
