I purchased 4 panels to get the full look in my newly decorated Master Bedroom. The 1st two panels were ok but 1 had imperfections - 4 small holes that allow light to pass through. I had to move it on the outside wall so the light wouldn't filter through. The 2nd set of panels I purchased - 1 was ok but the 2nd one was folded wrong. The creases that are left are permanent and so now unfurled, it doesn't close properly or lay properly. The creases give it a sloppy, weird look. I can't move it around since the other side has the hole and I don't want it hanging on the bed side.                                                                                         
  Overall, the product is just ok! It's a pain to return so I kept it, but, too expensive for these problems! Does it stop the light from coming through - yes but not entirely. I recommend others to shop around and get something else!
