My Samsung Galaxy S3 (incl. Case from Otterbox) holds bombproof in the holder. I have the support of the disc NOT my Skoda Octavia III (Model 2014) attached, but on the dashboard next to the steering wheel. Actually a good position. The bracket holds bombproof and does not wobble.
BUT, the suction cup leaves on the dashboard after 1x using a circular imprint on the soft touch surface. This imprint is still visible after 2 months. I suspect that it will not go away. I'll fix the holder at least not again on the dashboard. So be careful with soft-touch surfaces. With hard plastic surfaces, however, it should be no problem.
If someone can give me a tip, how do I get the impression away again, I would be very grateful. Then I would still pack a star on it.
