While I like the look of these curtains and the fabric feels durable, I am only giving 3 starts because they are NOT ROOM DARKENING, in fact, nearly the opposite.  So, withholding 2 stars for false advertising.  If I'd known beforehand, I might have ordered them anyway because of the colors, design and price, but, if you need these to be room darkening, you will be disappointed.  Seriously, I could watch TV through these things.
