After trying almost everything in the book to find a decent phone holder, finally decided to just drill the dash for a permanent install. I had some success with the ProClip as seen in my other thread, but there were two issues: the air vent was blocked and even after a day the ProClip started leaning slightly in the direction of the nano arm. I don't know why I waited this long to drill (fingers crossed).

The MagMount G3 is no joke. It does not budge. I can plug in and disconnect my lightning cable with one hand - pushing or pulling does nothing to the phone.
