Not bad 387

Good quality finish.
Advantage BE drilled in the center, when a post is provided in the wall for this type of support, on the other bindings have provided only on the side. If this is to secure the only non-reinforced plasterboard, forget this type of support.
The level is unreliable, use a true laser or bubble level on the base.
Requires slightly loosen the joints, if not too hard to handle.
The vertical orientation is then set to tighten, unlike the horizontal which is free.
Depending on the position, the tv is not level, I have not yet found a solution to this problem.
If this support was worth every penny.
