The device is robust, solid, well built, well painted and comes with a variety of fixings allowing (for instance) curved back monitors to be mounted.
The desk mount looks as if it were designed for use in a military tank - it is 'industrial quality' - fortunately most of the heavy engineering is hidden when assembled and in use.
Cable clips are a bit flimsy and difficult to click closed but they are largely functional.
So, what is the problem then....
Pretty simple: It does NOT function!!!!! The monitor simply droops off the end of the rigid arm and swivels without control.
a) The last joint (presumably intended to allow tilt-up/tilt-down) is only a very simple 'friction joint' with smooth internal faces designed to slide smoothly rather than to hold in place. In order to hold the monitor vertical, one must REALLY force the giant screw as tight as possible with the hexagon key provided and it simply does not work!
b) The final mount pivots (presumably intended to allow the monitor to be in portrait or landscape mode) which seems like an advantage, but, it has no friction or click settings so the monitor simply turns each time you touch it - like switching the monitor on/off!!
What a pity they went so far and spoiled it by simply not thinking about it's implementation/usage properly.
You would have to re-engineere the joint(s) perhaps with some simple drilling and pegging. If you are not prepared to do this, you may want to think carefully about purchasing it as your expensive monitor will probably be flapping around rather than held firmly.
