Very strong fixation, never default setting for now. If I vacuum the kitchen table, I lift the table with the cup ... I tested it on the door of my car without worries up to 110 km / h. I still foresee a precautionary safety leash (in case of shock, for example). The suction cup and put in a simple and effective mechanism. It is a light coat annoying if you sucker with the camera already mounted on the cup, but doable without problems. The suction cup comes with different fixations that combine poru gopro put in all possible directions.
