Otherwise, there are no problems - it holds 2 monitors 27 'diagonal. Copes with the main function - it frees up space under the monitors. Different pros: Ease of mounting, all adapters and different bolt options for mounting different models of monitors. Cons below: It is difficult to unwind if you need to remove one part. That didn't work out, unfortunately. I wanted to move the monitor closer to the wall, removing one "knee", but it did not work out.
