ONKRON is probably the best company for brackets. Never failed. I bought 2 pieces, hung both, one TV 55 diagonal, the other 40 with something - everything is fine. The only thing is that the instructions indicate the position of the central mount for the TV in a very strange way. If you follow the instructions, then the adjustment of the vertical tilt angle will only be towards the ceiling, which is rather strange. I need a slight downward slope, so I hung the bracket on the other side, again there are no problems. There are cheaper brackets, but if you want good quality - take oncron.
