Well, not so great ....

After I now bought and mounted some wall mount, there should be one at this time is not so expensive. Then ordered on the basis of these reviews. On first impressions very stable, moderate, a lot of weight. However, inaccuracies, misplaced screws, plates easily bent. For installation you must first disassemble the bracket. Despite careful assembly then wrong. By washers then tedious alignment. Duration: significantly longer than with the other supports.
Oh: Screws for Samsung TV actually too long (Fortunately I had from other holders even shorter since), supplied dowels bottommost quality. Advice: better to take the same fishing or Mea dowels.
Conclusion: Cheap is often more expensive.
Although the job done, but I would not buy again.
