1. If your monitor weighs more than 5 kg, then this option will not work for you 2. When strengthening the vertical fixation, the bolts creak and almost burst. 3. A monitor weighing 5 kg simply cannot stand in a fixed vertical position and fall down, despite the fact that it was twisted as much as possible, again everything creaks as much as scary. I don’t want to say anything bad about the company, but this particular model failed, although many products of this company have problems with vertical fixation.
