This mount holds our old 42" LCD display in a kids play room. The display is heavy and I was concerned at first but once minted and hung it was clear that it was plenty stout enough. So far I've ordered two different display mounts and several speaker mounts, I've been impressed with everything so far.
I purchased two of these, one for a TV that must be mounted on a wall that's not flat (it has a 170 degree inward angle), and a computer monitor.
I thought it would work great, since the TV I want to mount weighs less than 20 pounds. It appeared that I could use a stud and mount two bolts in a vertical alignment, since I can't use two adjacent studs.
Well, I received the thing and the mounting holes aren't vertically aligned - they're in a three-point formation. This means that only one of the bolts can be mounted to a stud (if you want the thing level.. you could rotate it a few degrees, but that would look rather terrible).
It did come with some cheap wall anchors (3/8"). However, when I used these, the bolts don't tighten into the anchors. I installed the bracket using these anchors, and hung my TV up.
I noticed it looked like it was tilted down slightly. Then I decided to adjust the angle. That's when I noticed the sag. The top bolts were sliding out of the wall! This is a horrible design flaw - why can't the bolt holes on the mount be vertically aligned? The mount is only rated for 55 pounds, so it's very feasible that this would work. Nope - they have to be in a triangle formation.
I then proceeded to remove the TV from the mount, and pull the entire assembly out of the wall. Using one hand. It was quite easy.
