Review on Height Adjustable Universal Projector Ceiling Mount Bracket, Black 16.9—25.6 inch, compatible with BenQ, QKK, Epson, Optoma, DR.J Projector by Marcus Braunstein

I had no problems with that. Maybe some drywall anchors would be fine, but I would never use those old anchors when there are EZ anchor types now. So if they sent 4 of these that would be the only improvement that would impress me I think. I originally intended to mount it on the ceiling but decided that using a wall extension gave me another important facility. I'm glad I did. (I lost 2.5 inches this way if I wanted it to be as close to the ceiling as possible, FYI) It's not necessary, but I found an axis at the center of gravity (centroid) was a good idea . I calculated this by using a AA battery on a table and placing a projector on it for each axis. One downside was that it wasn't perfectly square when expanded, and that's the only axis adjustment you don't have on this one, so I got around it by just pulling hard on the side to get it square to bend There were holes in the projector mounts with a fairly large diameter, so I had to adjust a bit. I also like that it's easy to remove from the mount (I had to blow out the debris somewhere in the block lenses). But considering how long it took to align the image perfectly, I don't want to do that often). I agree, I'm a perfectionist. I was told. The only reason not to buy any of these IMO (instead of installing a shelf or side table etc.) is that it will most certainly take longer to set up. If I knock it out of alignment, it takes much longer to fix than if it were on a shelf or on a table. But it frees up a lot of space compared to another piece of furniture or a giant TV! FTW projectors! ...and you can center it perfectly since it can be above you (for us cheap guys with no horizontal keystone). Of course, this has nothing to do with the product, but with the type of attachment. When hit, it will wiggle for a while before calming down. I have low ceilings, but most people won't have these problems. You can run cables in it, but I didn't. I wanted to make it easier for me to play around with cables (anyone did NOT have an HDMI cable connector? I'll never understand how a cable that never moves dies). Compared to some other designs I looked at, this one had an extra axis of adjustment. I would like to have all 3, but it should also be solid. And not expensive! So a great buy I think. Ignore the wooden plank in my installation. I wanted the hostess to be happy with just two small holes in the rivets. Hope this helps someone decide!
