At this price, unbeatable. Gondola a little down, nothing frightening if we ca see disappear with time, but really a small ripple, nothing wicked good. However I get a star because I thought that it was intended to be the ceiling. Indeed in the instructions they explain how to fix it: simply put 2 hooks into your ceiling and hang the screen in the holes. It really took me 2 minutes (good when one is equipped with tools ca facilitates the stain ...) ... But the hitch is that you need to pass your hooks into the same holes as those for fixing to a wall, thus at the back, which is that once suspended, with the weight distribution is slightly inclined and the slot for unwinding is not facing the ground, but backwards. So when you unroll it slides on the metal. I do not think it could to damage the screen but now ... I have the feeling of having bought a screen is to be placed on a wall that can be put to the ceiling by fiddling.
