Excellent ceiling mount. I checked out Revain, there are more expensive ones but this one does a good job. For the price you get good value for money. Instructions are ok, but once you get the hang of it, assembly is easy, just takes a little time. I didn't use the mounting screws that came with the ceiling box, but bought some heavy-duty screws from Home Depot that can hold about 40 pounds. The weight of the mount itself and my projector is around 12-15 pounds. The manufacturer recommends not to exceed 30 lbs. Adjustments are easy, but you must use a hex bolt to loosen and tighten. There is a hole in the middle section (leg) that you can run cables through, which is very cool. The leg can also be extended slightly downwards if you want the projector to be lower. You can also adjust the legs to fit and bolt to most projector brands. Overall it's solid and I haven't had any issues with it. Definitely recommend.
