My suction mount is often taking off the windscreen when the temperature goes up, so I was looking for an alternative, and am turning to this it based on many positive reviews. What a disappointment using this medium! Already the ball that clips in GPS support is not exactly the same size as the original media, suddenly the GPS (3790) moves (too) easily. Then I thought of the support 4 small bags filled balls would logically be flexible to properly match the shapes of the dashboard, and no, everything is too rigid and it is impossible for me to position the support on my dashboard without this motion. Probably useful to an array of perfectly flat edge, otherwise go your way!
