I put this in my car's grille and it broke a few internal ones. The phone is heavy, so the ventilation grille pulls down. The good thing is that it has a small footer that prevents it from falling over. In general I like it.
Pros
Traditional mounts require you to have a firm grip or stand on the phone every time the phone is connected or disconnected. This magnetic mount doesn't require any pulling, pushing or any kind of force - just install and go!
