Overall it worked perfectly. Instructions were a little unclear, but I have mounted these brackets before and it wasn't difficult. One lag bolt did snap, however. Changing these to ones that are a little more sturdy would help. I was able to finish the project with a bolt that I already had.
It's a great mount for the price but the tilt screws didn't work so there is a small amount of vertical down tilt to the TV( 42 " FYI ). Luckly I mounted it high enough so it won't be of concern, but I can understand where people could be upset thus why i'm giving it 4 outta 5
The arms are kind of small and thin for the weight rating but the biggest problem is the tilt up and down, I wasn’t using a heavy tv at all but I could not tighten it enough to keep the tv straight up and down. I ended up driving some screws through the mount eliminating the tilt feature
I love the fact that this mount extends very far from the wall and only needs one stud to do so. but I was disappointed when I could not keep the tv flat especially with all the adjustments provided. The tv constantly tips forward. I had to put a self tapper screw in to kept in place. Very disappointed.
