Question about Sunne Pro300s

First, the projector is mounted upside down with the screws. The beamer can be detached from the ceiling fixture relatively easily, but the setup must be adjusted accordingly...The beamer can be detached from the ceiling fixture relatively easily, but the setup must be adjusted accordingly.

I have to disagree with the previous speakers: to detach the projector from the bracket, you only have to loosen a Phillips screw and slightly unscrew the locking arm, after which the projector and base plate can be removed and pulled out. I would calculate 3-4 minutes each for dismantling and hanging up. After hanging it up, it must of course be realigned, which also takes time. But the disassembly or assembly itself is quick. I had to take it down a few times at the beginning because I changed my setup several times.

Is there a ceiling mount where the beamer can simply be slid in and easily removed again?
