All in all, the mount was delivered quickly, many screws and accessories (such as distances for curved screens, etc.) here which is very handy in itself. The bracket itself seems solid and have full confidence in the processing - Top.
Even with all the accessories, however, lacks a drilling template, so it was relatively difficult to draw the drill holes, as it needs to be kept on the wall without Verutschen yet. The manual was also not sooo helpful, for me at least they could be more clearly defined. The "spirit level" which is please forget, is not just, unfortunately only realized after hanging - be sure to use your own great spirit level!
The television then holds quite well on the bracket, watch out that the screws are firmly angeogen - otherwise it easily slips on the rail, but tightened he notes.
In summary:
+ Well made, no apparent weaknesses
+ Swiveling 180 degrees (at 40 inches no problem with larger, it will probably be limited by the width.
+ The price may be folded
~ TV on the plate slips if not completely tightened (but not really screw acts designed to keep anyway) and you turn the screen
- Drilling template is missing, marking is really awkward
- Use your own water balance, not to be used provided
All in all it is great for the price, only the hanging could be made easier with better accessories / manual.
