I use the canvas for several months now to my complete satisfaction. The roll-up mechanism works perfectly so far. The housing is made of thin sheet metal, is certainly no beauty, but for the price ok. The first delivered canvas showed irregularities, which was visible as disturbing stripes in bright projection. The contact with the company was prompt and very helpful. The canvas was replaced without difficulty and free of charge. The suspension in space, so a bit away from the wall, will require some rework. Here I have two angle mounted. If you hang the screen with the supplied carabiner at the ceiling, the housing is crooked and the screen rub against the sharp metal edge.
