However, we had the problem that the hinge to adjust the vertical angle of inclination could be tighten difficult. It seemed already to be rock solid, the screen is but folded down. Only by brute force and ordinary tool (instead of the supplied Allen wrench) he had to stop them.
In addition, the horizontal arm can for example not work so that the screen directly to the vertical rod. Because I would have liked a little more flexibility. The height adjustment, which probably is the most common surgery in use by more than one person is not "just" possible.
Overall, the holder for the price okay, but not outstanding.
