In terms of the top review "the monster ..." I can add that the support very well fixed a mobile phone / smartphone not only upright. By the rotating mechanism, the smartphone can also rotate horizontally.
Of course, a smartphone would edge more resistant to shocks, but the gripper arms pull strongly enough to hold a smart phone in horizontal. Depending on the arrangement of the cell phone charging port, and an inserted while driving charging cable between the gripper arms for additional security can ensure against slippage.
Of the two gripper arms can be one pair smoothly adjust and lock, the other pair operates with a continuously variable traction mechanism, which the user must pull apart with little effort. Leaving these gripper arms going, snaps back the pulling mechanism.
The two lock levers are stiff, so I mostly just fix the smooth side and let the other hand, keep themselves side by pulling mechanism.
The material of plastic is probably not hold indefinitely. Even by the applied force when adjusting the arms could eventually cancel. In the event that it comes to that, the manufacturer has settled a pair of spare grippers foresight.
The suction cup holds been rock solid on the car window.
Conclusion:
For me, the safe maintenance of heavy equipment and the opportunity was a smartphone clamp buying criteria. Tablets and smartphones may be principally vertically as well as horizontally rotate. With a smartphone you risk just slide down, which is unheard of by the strong grip arms with me.
The plastic may not last forever, however, the support is strong, functional and on Amazon, I have no better alternative.
