The phone itself isn't magnetic. Instead, you place a metal plate between the phone and the case it sits in. That looks a little awkward as we went with a lightweight case with a clear back. But once in place, that is how the phone holds on to the mount.
You'd think the unit might fall off when you stop the car quickly but so far so good. It works really well and the phone pulls off easily when it is time to move on. That last part is my wife's favorite part. This one might be a keeper.
