Review on Optoma BM-5001U Low Profile Black Projector Ceiling Mount for Optoma by Joseph Flamm

Great for all Optoma projectors and may fit some other brands if they are smaller. The only issue I had was that the buttons are soft plastic and still wobbled/stripped even when using a very large Philips head. I had to use pliers to adjust it, which was difficult because it was so close to the ceiling. In the end I got what I wanted. and the quick connect function to remove the projector saves you cleaning the unit or replacing the lamp. I'm very glad I bought this. If they turned both knobs back it would be a lot easier. You could make a quick connect adapter to fit any other brand.
