To wall mount itself: sufficiently stable if the bolts attaching (for wall mounting) directly behind the suspension points flexes at all by anything. (You can easily move the TV sideways, thanks to the rails) -> recommendation
Included Screws: Screw in two different lengths are included, together with spacer sleeves. Well, who are too short (not grab) and the others are too long, so you do not Karft / form-fitting can fix the holder ski Ennen. (Mind you, the UE60ES6300) -> NOT A RECOMMENDATION
(Note: I have then the "old" used screws from my Pioneer plasma, which matched perfectly ... otherwise I would have been in a fix ...!)
General: The wall mount is so flat that the cables (HDMI, fiber optic, USB), which are currently plugged from behind, bent as they or partly directly to the wall resting on the lower rail. Solution to this problem: tilting the TV and spacers on the bottom edge of the TV. This is not an optimal solution, but can not be helped. -> NOT A RECOMMENDATION.
Now, an inherently good wall mount but not for Samsung UE60ES6300 recommended.
