At first I had some doubts whether a retractable wall mount supports a 55 "TV safe. After installation, I can say that I now have no doubt about that. The TV hangs Bombenfest and can be extended and swing well.
The only problem I had during installation was that the frame of the wall mount concealed exactly the power connector on the TV. Actually, the frame should sit centrally as possible, but you can slide this frame a few centimeters to the left, and it might fit wonderfully. By "bottle" Mounting the TV hung until something goes wrong, but that could be compensated for any problems with the provided screws.
The Kabelfürungen are more or less useless for me. Maybe it is also due to the large number of cables that I connected, but you can lay some cable in the guides and then fix the remaining cables with cable ties. Then everything works fine during deployment and retraction. Through the routing guides an estimated 8 cable to be laid, but only if you have above and below the mounting holes in the wall. If like me you just above a hole, then you can linnks and right only two cables accommodate. For me it's power cable, satellite cable, network cable, 2x HDMI cable, game console and a USB cable.
The thick cable bundles the wall distance of the TV is about 8cm, but maybe you could something else have done better. I've had enough so it looks very good.
My TV, I can swing a little more than 45 degrees when fully pulled-out arm. Have a Samsung UE55F6500.
