I've been wondering that this wall mount has got seven 5-star reviews, so I bought it for a new kitchen flat TV (21 inches). She may be processed cleanly, but we have Gerbraucht with my husband 2 hours until the TV finally hung on the wall! It was an endless fumbling - the front piece with the TV back to the top of the wall to bring along! And at the end tilts the TV under his (really low) weight down. This is due to the large screw without slot and mother that you see in the picture right side: they can attract only with a special wrench, which was not present in the mounting accessories. Luckily we had the right key, but it has brought nothing: The TV hangs upside down as it were always down. Annoyed, I finally just put a pencil between the lower peaks and the joint and since then the TV hangs straight. We must no longer touch him only, otherwise the pencil falls out. :) If the wall mount no longer buy.
