Usable and robust but low end and not practical

The robustness is not a problem for these models that simply hang the TV against the wall (without arms), given the current TV weight.
Left to drive prices down, why incorporate a level bubble that serve only once to the installation? All handymen equipped with a drill and a drill 10 necessarily also a level ...
Above all, the bubble up here is completely false (0.5 cm false level on the length of the media!) And stamping the frame to insert a slightly deformed part!
The lack of precision is the same on the folds of the frame sheets: once assembled, some-thing not really rectangular is obtained, which does not rely much on a flat surface.
I did not bother to return it because it will still the case, and that ugly crooked trick is no longer visible once stuck behind the TV.
Another big flaw, but then I feel that it covers all models and all brands yet because I have long sought: none of the products I've seen seems to involve setting up a false level due to openings in the wall. The windows for screws are drilled vertically instead of horizontally on one side of the support, it does not cost more and it would be fine ... For my part (no question of risking to be with a TV that looks), I simply used other attachments than those supplied, a smaller diameter, and added washers under the screw heads. it gives the game to adjust, and my expanding metal anchors are best suited to BA13, and just as their oversized 10x50 lag bolts (or 60 I do not know) to the weight of my TV!
I confirm that announced the thickness (4cm) is false, rely almost 6 cm with the spacer washers provided, or nearly 5 cm cheating by putting them between the screw head and the support rather than between the support and your TV. Personally it took me 4 to 5cm to leave room for cables, so I "cheated" and that's fine.
Last surprise when to hang the TV:
I counted adjust the tilt to 0 (therefore well vertical). Excluding once the hooks stuck in this position, you can not hang as you tilt the TV to enter the support, and it comes up in the wall! Put the spacer washers might have avoided the problem in my case, but certainly not for everyone, because if the top of the bracket is away from the top edge of the TV is cooked anyway ... finding He must hang in a tilted position, and then adjust the tilt. Super convenient to then tighten the nuts that lock the tilt: the cranks that seem a good idea in the photo do not have instead of making a complete revolution between the TV and the wall, so you have to squeeze almost thoroughly before hanging, and plan to finish tightening in less than a quarter turn once in place, slipping a hand as can be.
Conclusion: I wonder if the people who designed this product have tried ...
I probably would have done better to take the model without tilting (in one piece frame and screw tightening unattainable), but the thickness of 3,6cm announced asked me problem. Except that if the error of 1cm is the same, it would have been perfect!
