Slightly unstable

Good price, good goods. Packaged as you want it to introduce. Accessories complete, without complaint. But I find the bracket a bit shaky. I use them for my LG Beamer bring upside down on the ceiling. Because nothing will fall, so much seems certain. The lateral retaining screw is what makes it a little wobbly. Especially when projector it is important that just moved nothing. But that's not so sure. But since it's a camera mount, you should miss the part already good grades.
