I'm resurrecting this thread to ask if anyone has experience with vibration damaging their iPhone' camera and or with the Quad Lock and its Vibration Damper as a solution.
Given Apple's warning
about vibration from high-powered motorcycle engines damaging modern iPhones, I would not mount my iPhone on my M3W. The S&S engine delivers world-class shaking as we all know. A vibration damper would need to be extraordinarily effective to dampen that, and it would be an expensive experiment to run if a damper is not effective!
