I was skeptical at first whether you really get a decent support for so little money. And then they came ... super! Clearly one does not perfect all-round finish, but as the obvious place, are more likely to have been spared. So for example, the part at the top, which will disappear under the covers. The bracket makes any event a very stable impression. One can tighten all the screws properly, so that nothing crazy. The holder makes a massive impression.
I use them with the projector ViewSonic PJD7820HD. Since you only need 3 screws / arms.
