Awesome, I really like the ProClip vent attachment idea, but centered over the flasher button. On our recent road trip I had a spring-loaded holder for my phone mounted to the left air vent, and it partially blocked my view of the clock and made the sound system volume knob more difficult to reach, with my iPhone 6. On hot days, long trips with the phone constantly plugged in, I think it's good to have the phone in front of the air vent to keep it from getting too hot. But otherwise I think it actually makes the phone too cold. At one point on our trip, with my phone in the mount, the battery level dropped suddenly from 16% to 1% and then died. I think it was because the A/C made the phone battery too cold. Perhaps being in front of the flasher switch will be a good compromise for helping keep the phone cool on hot days, but not get so cold as to kill the battery at night or on colder days.
I assume the magnetic holder will keep the phone in place despite going over rough roads or with other vibrations inside the car?
