Somewhat cumbersome in assembly

The fact that I got my Sony at the end still on the entablature mounted, I would not have believed after the initial difficulties during installation. Once mounted, the mount done its job but are not limited.
Why was the Assembly so difficult? The arms can mount on different ways to be screwed together, so that they fit on different possible models. This is of course in terms of flexibility a good thing, makes reading the manual but not necessarily easier. In general, the instructions could be better. To fix the holder to my device I had to eventually vary from two installation options outlined in the manual and improvise something. This variant seems stable, but I wonder to this day if it was so intended.
Anyone who has a 42 "Bravia should accordingly better look elsewhere.
