Looks interesting. It will be awhile until I upgrade to a phone supporting wireless charging though. I'd guess such a cradle would have to be wired to be off with ignition off or to a switch.Now they are designing something we can use.
Have been using bike mounted smart phones for half dozen years and 100k+ miles. Never an issue... except for the one time I dropped the phone doing 60 on a lonely deserted Utah highway. Picked up the pieces and put it back together, still good. Few cracks in the screen, but useable. My fault, not the mounts.I have something like that for my car vent. I wouldn't trust the clamping mechanism without a carpeted floor beneath it to catch the phone if it drops.
And the stories of smartphone cameras failing from the smartphone being exposed to handlebar vibrations, would keep me from even considering it in the first place.
