The articulation of the support is flexible but not too much. We really shot to make it move. The whole is very stable.
A significant point is the ability to finely adjust the position of the TV when the bracket on the wall. You can get exactly the position and angle you want.
The distance from the TV to the wall was a little surprised. I thought she would be lower. Between the screen and the wall, the support being in the folded position, allow a gap of 14 cm (with a Samsung LCD).
The installation instructions could have been a lighter hair but remains quite understandable. It is in English only.
