It was installed on a brick wall without any problems and nothing outside the package was needed for the installation.
It definitely requires two people as it is too heavy for someone to install without help.
It has several adjustments that can correct even small deviations you may have had when screwing the base to the wall.
A 65'' Samsung was mounted on it and it can turn completely to the side, and it seems that it can easily support even the larger/heavier ones it is rated for.
Over time, its durability will show, but the signs are encouraging.

Sturdy construction, the tilt is quite large, negatives: the plastic on the arm that opens a bit, I opened it to pass the antenna cable and it broke at the screw, also the instructions with the rubbers and screws are irrelevant

It's a beast! It will stay on the wall with the next TV as well. Sturdy and user-friendly, it fills you with confidence!

Very satisfied with the sturdy construction. I did not install it myself but a professional did. The tilt is sufficient to see from one end to the other. It protrudes quite far from the wall to give a better viewing experience to the viewer

I got the stand for Samsung Smart TV 85" 4K UHD Neo QLED QE85QN85C HDR, 43kg.
Heavy and sturdy construction, it takes 2 people to install the stand and the TV but in the end it fell "short".
I give it 3 stars because even though all the screws are tightened well, the back is solid iron, you can hang on its double arms and it won't move at all, but the final arm is very light resulting in the TV leaning a bit and causing a lot of vibration, as if you haven't tightened it well. So, if you want to clean the screen, it goes right-left and it doesn't please me.
Of course, the TV will not fall under any circumstances.
I had experience with 50" TVs which are relatively light. I bought it for 105€ but I think I should have spent close to 200€ so it wouldn't move at all.

It is possibly the only base currently available that can accommodate all TV dimensions that exist or have existed in the market. This particular one is not just able to withstand the weight (I have a 65" plasma TV weighing 45 kg + 10-15 kg for the base), but it is also the one that can properly fit the dimensions of the holes on the back of the TV.
Overall, it has all the convenient adjustment features that such a base can have.
The only negative aspect for my case is that I cannot pass the cables through the designated positions.
For installation, I have used 10mm screws instead of the 12mm ones included in the packaging, and everything is fine.

It definitely requires two people to install it, as it is very heavy.
Very good quality and very sturdy.
The cable management channels could be larger in diameter and more easily accessible.

External construction and functionality are great.
As soon as you open the box, you realize that they didn't write "Heavy Duty" lightly (pun intended) on top.
It is not easy to find a wall mount for these TV dimensions, if at all, that extends up to 1m+ from the wall.
Due to rotation and easily adjustable VESA mount, it can handle some small mistakes in calculating the appropriate height pre-installation.
The only thing I would like is a little more space in the cable management tubes because now each one (1 on each side) can fit a maximum of 1 HDMI cable inside, so even with 1 input + power, cables need to come down from both arms. But, well, you can come up with a little trick and you're good to go, other more expensive ones don't have any at all.
Great buy, absolutely recommended.
