Beautiful, thick curtains.  Great if you love birds (which I DO!!).  They filterdim the light a bit, but calling them room darkening is a bit of a stretch.  Thermal and noise reduction claims seem to be accurate.  Deducted stars because there are permanent marks on the curtains where they were folded - something you wouldnt expect for the price.  I got another set of different curtains by the same brand, also from Wayfair, and they have the same marks.  This is my first time ordering from Wayfair and it kind of leaves me with the impression that you cant trust the quality of the  products they sell.  Pretty disappointed - both panels in this set have the marks, which makes them hard to hide when you want to have the curtains closed.  Not sure I will order from Wayfair again if quality cant be trusted.
