Good but attention to the installation instructions

This product complies with the description and installs easily.
Note that the screw fasteners (M8) on TV are slightly too short for a Samsung 55 ''; it is necessary to provide for other although three types of screws are supplied with already!
On the assembly instructions, the orientation of the bottom rail of the frame to the wall that arises is misplaced. Unfortunately it realizes once the assembly mounted on the wall; a reversal of this cross redrilling and involves repositioning fasteners ... well, we forget quickly ... The consequence is that one can not properly secure the TV against tipping.
Finally, a horizontal stop each bracket side would have been nice to avoid slipping on impact along the wall ...
In short, it remains to detail, it's still a good product.
