I verwene him for my Epson EH-TW9200W. For this, rather large projector, the maximum hole spacing of no longer enough. Since the sale in the description, which of course is my problem. But it was not really great, since I use an adapter which was left at a TV wall mount.
Why only 4 stars? Indicated a maximum load of 20kg. I also believe that it does not break with such a burden. But he's still handy for so big / heavy projectors, dare I simply doubt. My projector has almost 10 kg and I feel the mechanics still Ok but rather borderline. Due to the large forces, the whole construction never feels truly at rigid and therefore stable. Due to my Scope canvas I have regularly, depending on the film format, adjust the zoom and the lens shift and I'll never do this without violating hold, since otherwise could adjust the alignment. The screws are pulled as hard as I do not trust it to me without risking breakage. My additional adapter is completely rigid and does not cause.
To be fair, one should emphasize, however, that other holders also can not do magic, and most owners are not constantly rumstellen the projector. I think the ceiling bracket so highly recommended for when the projector is not too big / heavy. Definitely a great price / performance ratio. I myself would probably not buy me one more time but because it hangs now, I'll be well clear.
