I'm thinking about getting a mount for the OP3 for my car and truck. Curious what everyone is using. I'm looking at the Scoche MagicMount but I have two concerns. I don't drive on highways very often. Most of my commute is on secondary and tertiary roads that are honestly not in great condition - very bumpy. I'm first concerned with the vent mounts potentially breaking the vent in the car. Is this an issue? It seems that would be a lot of weight hanging on a thin piece of plastic. My second concern is with putting on - well really removing - the metal plate. I don't think I'd put the plate on the case due to concern #1 - very rough conditions so I'd want to have the plate on the phone. I believe even with the Otterbox case there shouldn't be an issue with the magnets holding but looking for some info from someone with experience on this too.
