We installed the TV together, it took about 2-2.5 hours, so it was very inconvenient to fix it.
The kit includes dowels and self-tapping screws 6 cm (plus still different ones), I was afraid to put such blocks for the foam block, I bought 8 cm.
Pros
The bracket consists of several parts: the part that is attached to the wall and the retractable parts are strong and rigid. The fastening to the wall is wide, between them is located the electrical wiring. TV 65 inches (21 kg) withstand.
Cons
The part of the bracket that attaches to the TV is made of thin metal - it doesn't feel solid.
The TV hangs, but if you think about it or touch it a little, it immediately begins to oscillate.
Regarding the installation - either the installer did it wrong, or it was all very inconvenient: they divided the bracket into 2 parts, installed one on the wall, the other on the TV, and then they had to be connected - it was very inconvenient, because everything is connected through a bolt (that is, you bring the TV to the wall, try to find holes for this bolt, then you need to hold the TV and tighten this bolt).
