After I unpacked the curtains, I was initially a little puzzled how thin it felt material and the like because to darken the room reasonable. But the test with a lamp brought clear then, because obviously the material is so finely woven that the majority of the light is actually held on the show through. It is achieved not a complete blackout effect, however, is estimated to absorb something about the 80-85% of the light, so it is still inside light enough to find your way without a flashlight at the same time is dark enough during the day to sleep comfortably. As a shift worker I was extremely important.
Since I use a regular curtain rail, I first had to equip the curtains with curtain roles. This worked quickly and easily thanks to the sewn Kräuselbandes, but pushed me buying this for the first time ill on: The ends of the Kräuselbandes with two curtains are obviously so bad processed, that the threads, in which you hooked the curtain rolls, from the curling ribbon detach and thus no longer leave the rollers on the ends of the curtain hook. Result of this is that the suspended curtains hang down according soggy at the ends. Since my return shipment came in time inconvenient, I simply even resorted to needle and thread and itself improved.
Due to this defect 1 star deduction, otherwise the curtains for the price look quite neat and fit for purpose.

ADDENDUM:
As myths Metz remarked graciously, I have the curtain rollers mounted probably not working properly because they do not * between * the two Kräuselschnüren must be hooked into the Kräuselschnüre but in the tabs, so the error was not the product, but with me. For this reason, there are subsequently still 5 stars.

Finally, I recommend, however, for the curtains in 175x145 additionally required nor plumb line, as it due to the material flutter relatively uncontrolled even in light winds.
