This arm has been just what I needed, I wanted to install a smaller monitor (24") on top of the 32" monitors to be able to have separate some applications, I thought the arm would not reach the height over the 32" monitors according to the specifications (20.87" | 53 cm ) that showed at the maximum height level towards the knob, but it happens that, when installing it on the table, it reached 25.2" (54 cm) from the table to the knob, which allows me to manage and view the 24" monitor without problems. In addition, I have a range of 1.2 " (3 cm) more in case I want to raise the monitor a little more, thanks to the design of the clamp that is fixed to the table, and this 1.2" are good because although to reach this height the clamp reaches the edge of the arm as you can see in one of the photos, lowering this clamp those 3 cm is something that I'm going to do to reduce a bit the tension, even though in the moment and how it is installed, it is not really generating much more tensile force on the bar and the table as it might if you had your arm extended much further The materials are very good, and I was surprised by how well thought out the design of this arm was. It has plastic foam at the base to protect the table. I was also worried at first about the clamp which hold the arm to the round metal bar was made of plastic, but my doubts were dispelled, and the design of this clamp seemed very good, strong and functional for installation. The strength to hold the monitor both on the knob, on the arm and from the clamp towards the bar, I can say that they are very good, I have not had any problems with them, I'm certainly using it with a 24" monitor and not with a much heavier 32" one, but for my needs and what I have tested it for, the arm fully meets the specifications and functionalities described. The only detail I found about the arm is the bottom part of the cable holder did not fit, but it is really totally unnecessary and is not something that affects at all my opinion of this arm.
