purchased to replace a medium that "bringuebalait" constantly, I am very happy with the product. I use a Sony Xperia Z and iPhone 4S, no problem with both of them, as well as portrait to landscape position. The party starts on the aerator being covered with rubber, the support does not move, does not vibrate => therefore no noise The support is fixed properly on a ventilator grilles Golf VII, but not yet tried on other cars. The jaws are covered with rubber, no risk of damaging the phone again and no vibration. The phone installs and removes easily even with one hand.
