Review on Versatile 2-Pack YiePhiot Mini Projector Mount Stand for QKK, DR.J, DBPOWER, Anker, VANKYO, AAXA, Jinhoo, PVO, TMY, AuKing and More (175mm) by Jacob Kuntz

Just right for mini projectors. They are well made and the ceiling mounted bases are very easy to hang with the included hardware. They simply bolt together, and a mini projector bolts to it. If your projector doesn't have a hole for them, you're out of luck, they're so simple there's no other way to mount them. They're not super adjustable, they hang from a rod that only moves with a ball at each end, so you can't adjust the distance of the bottom rod from the ceiling. Overall though, this is a good option for a compact projector with screw holes to allow it to be hung.
