This is our second screen, so we have some experience: +++ Price / performance, especially if you want to have no engine in this size you will find hardly anything comparable; ++ Little odor, fumes disappeared much faster than our other; + - Has been with us in a bottom corner of a significant larger wave, but rarely interfere with the look; - Ceiling installation, no or incorrect description resolved, settled unfavorable angle, since the center of gravity of the screen away from the leads breakpoints to wobble undress. Without additional Marerial from the hardware store, with me about 30EUR, I would not mount the canvas on the ceiling. Wall mounting I did not try but seem designed more reasonable.
