Overall the mount was relatively easy to put together. Many reviewers complained about the fact that the mount frame had to be assembled. Without any guidance, this would have been true for me too, but the installation video on the Mont-It website showed exactly how to do it (very helpful). Assembly and installation went just fine, and so far, no issues with the integrity of the mount.
My only small complaint might be in regard to the tilt adjustment. As others noted, the mount seems to tilt almost all the way forward as-installed. I didn't think to tighten the tilting screws prior to hanging the TV on the wall... if I had, that might have prevented the "automatic" tiltiing. Once the TV was on the wall, it was extremely hard to reach the tilt adjustment screws. Because the mount is so close to the wall, you need a screwdriver with about an 18-20" long blade to reach them. But the mount being close to the wall is a "feature" of the mount and a choice made when purchasing the mount, so I can't complain about it too much.
