The statements of my predecessors, I agree with him. The following is from my perspective noteworthy: + Relatively easy + Through the very flexible support arms he fits nearly all mount images of projectors + Looks mounted relatively chic, holding plate when unhooking the projector from the ceiling relatively unobtrusive (especially if you painted the cleat matt white) - Einhakverschraubung bit too narrow for the hook receiver; but can be compensated with shims (metal / plastic) - Einhakverschraubung holds the beamer, but not locked him; therefore he is by tightening the screw still moved
