I was desparate to find ready made black out curtains that would fit our bedroom window. The only ones I could find anywhere online or in stores was on Wayfair. I was unsure of the color, quality, and the overall style but I was desperate for a good night of sleep (I'm on the east coast with an east-facing window). I am happy to say I am not disappointed. They fit the window perfectly, have a nice texture (I was hoping they wouldn't have a sheen - the do not). Also from the stock pictures, it was apprehensive on what kind of grey I would be getting. I'd say the picture ending up being pretty accurate. 

In terms of blocking light, these things do their job EXTREMELY well. My pictures were taken at the same time with full daytime light, so you can get an idea of how effective they are. Another nice feature is that the wands are reversible, so when I hung mine so both wands are in the middle when the curtains are drawn.
