This mobile phone holder is very nice. It holds onto the vent reasonably well, it's easy to install and remove and it hold the phone securely from three sides. The bottom shelf is particularly nice and cushioned (my previous holder did not have one, and the phone would slip down and sometimes out of the holder). The opening and closing is very swift and does not damage the phone.
It replaces a phone holder that sticks to the windshield and dashboard. It was not good for my phones, which tend to overheat when used as GPS. Because this holder mounts on an air vent, it's easy to keep the phone cool. It’s best mobile holder for car I have ever used and a must have accessory for your car.
