Super - when the TV again depends

I bought the bird wall mount for 47 "LCD.
There were at various screws, spacers and a description.
I had my problems with the description and needed my time to understand the individual steps. Thus, for example not pointed daruf how screwed on 400x400 VESA.
It goes - but is probably a hidden PISA test ;-)
Since I have plasterboard walls, I was not clear what to do. Matching dowels were not there. Although the bird web page informs that the holder can also be used to RIGIPS, but I found the information very sparse and did not long, what to do exactly.
In the end I have bolted the wall bracket without cavity wall plugs and directly to the holders of the Rigips plates.
There was the next problem. In the description of this attachment was mentioned by image and also specially in which holes you should use in such a case - but the holes on wall mount and description were not arranged identically (what is there at all descriptions).

But after a while the bird hung on the wall and the TV on the wall mount.
And then came to disappointment.
The wall mount can indeed left and right turn - and pull forward, but somehow I also thought that the tilt angle can be easily adjusted. But this is not so easy for large TV.
The tilt angle can be adjusted although minimal - but must then be tightened again. So any change that you can do alone.
Another shortcoming: Although the holder was just attached to the wall, the television hung wrong (not horizontally).
It turned out that the attachment TV <-> Wall Mount is to blame. After many attempts of solving, just set and again Festverschraubens, I had the whole thing finally happened and was able to enjoy the TV without disturbing walk on the wall.

The cinema experience is a lot bigger and subjectively, I feel, to have a larger TV.

The wall bracket itself is very stable. But if I look at the time I needed to adjust, then I can not accept the wikrlich at the price.
There on the wall-mount certainly one or the other improvement that can be made. It is not perfect.
And I guess that the problems in setting up with increasing television size increase (because then the slope rather perceives)

Now - in hindsight - I'm happy. But there were moments during construction, in which I was annoyed to have purchased a wall mount.
