The build quality is all top notch. Really high-quality materials, very easy installation and appropriate durability. Two Iiyama monitors with 27 inches for a long time have now been attached to the stand and have not yet had any signs of fatigue at the joints.
I disguise the brackets very often, sometimes on edge a monitor times (both times) is a hinge rotates from the desk to the sofa of the study, so that you can continue working comfortably from there. Minimum point of criticism: The cable routing along the inside could have been a bit better design. Have after the initial assembly, the cable inside along mounted - if now slightly change (or other additional cable if - as in my case - the monitors have multiple outputs and new equipment must be connected to the monitor), you would have to completely disassemble the part again - which, although not a very long time, but is annoying.
Have all now been solved with a transparent cable tie around the stainless steel arm - which does not look really chic.
Despite these small little thing a full purchase recommendation - there is in this area in my opinion is no alternative.
