Stable, but only conditionally swivels 180 °

Installation: Mounting the wall bracket makes any big problems if you're not too awkward. I am now not just the Home Improvement and I alone have done it without great curse, to attach the bracket to the wall.
I would recommend, not necessarily to use the enclosed screws and plugs for wall mounting. I bought some longer bolts and somewhat more stable anchor, but that gives maximum deductions in the B-Note. There are basically at all required screws and dowels.
Also, the Securing the TV makes no big problems. My TV has a 400x400 hole and this still fits with the wall bracket (which also corresponds to the specified).

Stability: I have the wall bracket is not too long in use, so I can not publish long-term studies. First, the holder makes a very strong impression. The joints are not so smoothly that moves the television at every breath of air, but not so stiff that it would be a show of strength to move the TV.

Swiveling: Here now is my only gripe. The stated 180 ° are possible in principle, but not in connection with large screen TVs. In my 40 inch television, it is no longer possible for him to pivot about 90 degrees to one side, since the arm does not come far enough away from the wall. For my purposes, it is still enough. The words "... to 52 inches" But we must refer to the maximum lifting capacity. When the size is likely to pivot but its very limited.

Despite the criticisms point there are 4 stars because the price-performance ratio is very good.
