Excellent. Easy to install. Easy to manage cables. Small distance from the wall. I have installed a 77-inch TV and it didn't give me the feeling that something would happen.

The review concerns the installation on a Samsung 65-inch TV with a VESA 400×300 mount.

4 stars only because you forget about the TV's ports. Non-existent space for connection management, even on a Samsung TV with the source ports on the right side (as we look at the TV).
If you don't connect everything you need before placing the TV on the stand, you will have to remove it at some point.
Personally, I connected everything and left the ARC HDMI waiting on the other end, as well as the optical cable and the extra HDMI. I plugged in a USB from a keyboard and connected a USB hub that I had.
Now, about the build quality...
It could easily get 10 stars. You might say it's just three pieces of iron, no big deal. The piece that goes on the wall is very sturdy, it gives you confidence, the same goes for the pieces that screw onto the TV.
The packaging includes a level and screws of various sizes (M6, M8 - short, long), as well as spacers, depending on the case.
For the M8 screws that I needed, I preferred to use slightly shorter ones than those in the packaging (which I bought) and not use the spacers.
I would advise you NOT to use the anchors included in the packaging because they are simply fake, and if possible, use 2-3 more turns.
Overall, I would say that the stand is a decent purchase for its price.
