Very good quality for its price. It is perfect for my Acer H5360 projector. Support is planned for a lot of different types of fasteners and should fit all models is a very good point. The manufacturer was rather exhaustive content provided on the side of screws, fasteners. This is remarkable since it has been more used reverse in general ... There are all necessary bolts, four branches provided (normally suffice while 3) and an impressive number of different diameters and lengths bolts to accommodate any device.
The only point I would have to blame is that the large bolt to tighten the mobile part (which can adjust the angle in any direction) is not possible when mounted. Difficult to fully resolve all this at once!
