Happy New Year Paul. One of your images here "Slapper Hackett" 😁. There doesn't seem to be a lot of people who have had problems with using their iPhones mounted in the M3W, so maybe our sort of vibrations are not the iPhone camera killer type or are you all using Quadlocks? The Quadlock vibration mount does look good but for my limited use maybe the X-Grip, with it's rubber mounting pads, is enough?
