Cultivated I have a 65 inch Samsung TV with 163cm diameter and 29kg weight. (Newest model Okt.2012)
At a purchase price of 3900 I would never take a wall mount for 29.
+ Wall mount very stable.
+ Plenty of accessories, screws for wall and for the TV with spacers
- Aperture very wakelig
- Cable guides fall off, are not to be used.
However, the negative points are I do not care, because the TV the mount completely covers anyway.
One tip: when the TV is to be mounted on the wall center, the holder has to be calibrated,
because an offset mounting plate success to the left. (mounting plate is then in the middle)
