Super Universal Docking

Have the docking bought to use the smart phone to my wife and my can.
The docking does exactly what it promises. Namely to keep the mobile phone in a certain distance and angle in front of the windshield.
This vibration is hardly noticeable and if one solves via the button on the back to lock the cell phone falls not directly out. In addition, it slipped only when compressed so that it is centered.
Super easy to use.
Tested with Galaxy S3, 4 and Iphone. 5
A product that does what it should and does what it promises and to the fullest satisfaction.
