Surprisingly adaptable but a light game.
I didn't know if it would be compatible with our almost no-name projector (Excelvan CL720D), and what a joyful surprise to discover that it is.The screws and bolts are complete and therefore not totally used because they are designed for other projectors.Be careful though, the vertical cylinder between the ceiling mount and the projector, is made up of removable parts.I have found that there is a little bit of play between the two pieces, but once it is fixed and adjusted, it is not very annoying. Tip: on the vertical cylinder, remember to turn the screws counter-clockwise so that the elements stay together (this is a safety feature).
