Review on DYNAVISTA Full Motion Universal Projector Ceiling Mount Bracket With Adjustable Extendable Arms Rotating Swivel Tilt And Low Profile Mount For Home And Office Projector (White) by Nathan Jones

The projector arms can be separately attached to the table and lifted for hanging. You need a screwdriver to tighten it, which is a bit awkward, but once fitted and tightened, it's very sturdy. I would say this is ideal for a permanent installation such as museums and shops. If you need to constantly adjust the projector's position, consider purchasing a projector with knobs to tighten. I gave 4 stars because the package does not include the M3 screws required for Optoma projectors.
