Canvas can be properly mounted on the ceiling and do as described. Screws and plugs for wall / ceiling mounting are included. Processing makes a good impression. Unfortunately, the documentation is somewhat taken just when it comes to setting the Endabschaltpunkte. But since there are only 2 set screws on the left side of the screen, you'll quickly find out how it works. Major drawback (and therefore a deduction of points): The canvas rolls at the edges slightly forward, so that represent the corners a little rounding. Since this is only a very narrow margin (the image area), I can live with it.
