The quality of these mounts are pretty nice. Fairly sturdy metal work. Very simplistic design that is pretty easy to put together, even though there are many pieces. They support some of my pretty heavy bookshelf speakers with no real problem at all. Biggest downside is that there is little to no adjustment available at all. They swing side-to-side and sort of up and down (via a screw on the bottom near the wall). No forward/backward adjustment or swivel from the brackets where the speakers sit, at all. They stick out from the wall about 8-10 inches. It's not a huge problem, but could be in smaller spaces.
