I had a bad experience with much more expensive medium, and broke guele on the dashboard with the phone above. Hence my skepticism to purchase extra. This support is just amazing, once in place it does not move, like glued to the windshield, like for telephone, comfortably gripped, it is perfectly maintained and does not vibrate. Osomount thank you, thank you amazon, and thank you to those who have me in their comments discover this great product.
