The Smartphone Holder for car windshield is very stable on many Smartphone devices (width) easily adjustable, really easy to handle using the snap Mechanismuss and a good sucker with single lever for sucking on the disk Raises with me super at the wheel and not fall the same again. The long grip lugs disrupt anything in the operation, have solved the problem by leaving the protective cover on the phone and the screen protection cover flap backwards, thus the device is thicker and you can the phone without interfering with the mounting tabs operate well .. For the price a good value.
