Review on 🔧 Heavy Duty Universal Projector Mount, Ceiling/Wall Mount Bracket, Max Load 45lbs, Extendable 15.7-23.6in / 40-60cm, Adjustable Angle, White by Josh Ulrich

Manufacturing tolerances are very tight, which means that if you do not tighten each screw as securely as possible, it could be blown out of alignment by strong winds. It was very annoying to set up. You hold the projector where it needs to be and tighten everything, and if tightening the screw doesn't cause it to go out of line, it will go out of line when you let go of it. The height adjuster is only tightened on one side, so there's a lot of play in the main mount, meaning a mere touch will throw off alignment. Each joint has equally poor stability, so it fails in all directions. From what I understand this mountain costs about $10-15.
