I've been using the brace for a month now and so far I don't regret my purchase.
Used screens:
The LG screens that I have purchased are known for their weak foot. At the slightest bump or vibration on the desktop, every screen vibrates to the point of boredom. Putting the screens together has solved a lot, but in the end decided to purchase a monitor bracket for 2.
After considering whether I would place the screens via the wall or on the desk, it eventually became a desk bracket. Although I am enormously charmed by the space savings of a wall bracket, the convenience and interchangeability of a simple desk bracket has been the decisive argument. I hope to switch to 27" screens in the future and then I won't have to reposition the brackets, just move them.
Package:
It arrived 1 day after ordering and paying for the braces. The box was a lot bigger than expected, in terms of weight it was not that bad. When opening the box, the explanation for this size was immediately visible, because the "arms" are 1 whole, supplemented with the standing tube with foot.
Installation:
The installation was very simple, place the foot on the desk and slide the arms (which come together at 1 point) over the tube.
All necessary keys were included.
The desk clamp consists of 2 separate parts which can be preset according to the desktop. The clamps fit well and are easy to tighten. However, I would be careful with glass tops as both the support and the clamps are bare iron without a rubber finish.
Cable management:
As far as cable management is concerned, everything is reasonably provided, clamps are included where 2 cables can be easily held per arm in order to absorb the movements. The cables come together on the holder and run down to my PC.
What disappointed me somewhat is that there is cable management from the screens to the tube, but no further provision to the foot. I used a simple tie-wrap but this could certainly have been cleaner. In the future I may have a hollow tube made to measure so that the cables can run through this tube. A DVI cable will probably not fit, but an HDMI probably will.
Fine tune:
As easy as the installation was, adjusting the screens was a little less.
In order for the 2 identical screens to come into contact with each other, the arms of the monitors must be able to move as far back as possible. Unfortunately, this was not an option for me because my desk is against the wall, which made the screens come further forward than originally planned.
The measured distance between the wall and the front of the screens is +- 18 cm, for screens with a screen diagonal of 23". With larger screens, the arms will have to stretch more so that they will hang closer to the wall.
The height of the screens is easier to adjust, although I do recommend doing this with 2 people.
By using a spirit level you can easily level the screens, although this will require some patience. After +- 3 weeks, 1 screen was slightly twisted compared to the other, a matter of tightening the bolts enough.
