Super price / performance ratio, processing ok

Although ceiling installation did not work as described in the assembly instructions, but went already. The screen is pretty flat, no waves, only on the sides of the rim bulges very slightly forward; but it is only the black surrounding rim affected, not the white projection surface, so do not bother. Canvas smell I can not detect any. The roller mechanism works well; furling he stays sometimes hang when the screen does not very uniform and relatively peppy upwards. Rattling at the end of the curl, when the trailing edge comes to the case, can not be avoided. All in all I am very satisfied with this price.
