The difficulty and the assembly time can be equated with a Kinder Surprise. The TV (42 ") hung quickly and easily to my (concrete) wall.
What I fande very helpful and what I had to smile a little, was the small integrated water balance, which you could just stick to the rail on the wall and could adjust so millimeter precision.
However, I missed 3 washers. Had I not had that at home, it would have been annoying.
I would recommend the bracket with no problems!
