Very good with some drawbacks
A support that fulfils its role well. I'm very happy with it, but here are some of the drawbacks:
The management of cables on each screen is just impossible unless you have tiny cables (if even that exists): A power cable + an hdmi cable + 1 USB cable, that doesn't fit in the passages provided (with 2 small plastic U's that barely fit. Even without the USB cable, it doesn't fit.
The fixation on the stand doesn't even allow the cables of one screen to pass through, so two...
The hardness adjustment of the joints (horizontal axis), even when fully tightened, barely hold my relatively small and light screens, I doubt that an 8kg screen (as indicated: 16kg for 2 screens) would not tend to nose dive.
As mentioned in the previous comment, you need a lot of space behind it (see picture)
The assembly instructions are only available on the internet, it's getting a bit messy!
The packaging is neat and the parts perfectly identified.
