These curtains definitely block out more light than my unlined off white curtain panel i have in between them. And they cost less than that unlined panel! It's hard to find lined panels for a good price, especially at that length.Great quality for the price and the shipping was fast. I did notice another reviewer say that in order to get free shipping, you had to purchase each panel separately and that's true. With 4 panels in my cart, shipping was $15, but with 1 panel in my cart, shipping was free. Though purchased separately, they all came together.To me, the color (silver/grey) is a little lighter than in the Amazon picture, but it's still nice.In the photos I took, you can see what they're like during the day (the sun is so bright in my bedroom, where I hung these) and what they look like at night. Again, the panel in the middle is a cheap, unlined panel, which still costs more than these.I hope this review helps!I ordered two sets and they even came the day before the promised date range. I was super pleased. One set is sage and just as I imagined. The grey, however, was a little off. You can see in the picture that one is somewhat more beige than the other only when it's backlit (as in the photo). I like that the curtains are lined but it just kind of dims the room. I may exchange this particular color for a darker shade like a brown.I ordered these curtains. They are very nice and love them. I paired them with multiple curtains. They look great and serve the purpose for what l ordered them for the living room. They were quality curtains for the price l paid. I have had no problems with these curtains and love them. Evidentually l order some great grey sheers to highlight the beauty of them. I paired these curtains with other curtains to hang up like sheers. I was not disappointed. Curtains in store such as in Wal-Mart cost much more.While these curtains are attractive, you can see from the attached image that they are definitely not blackout curtains. I bought them to create shade and insulate the greenhouse room in my apartment, and while they do provide some shade, the white foam backing is simply too thin to provide much insulation, so the room still gets really hot. Maybe a darker color might have worked better (I got lime green), but I doubt it. So, while they look good, and were a great price, they were disappointing since they're not blackouts as described.The color is nice. I really like the material, not cheap feeling or looking. I live in las Vegas and really needed some way to block out the sun. My house is mostly windows so it gets really hot. I put these up and they look beautiful, they let in just the right amount of light. My electric bill has gone down $100 per month. these things pay for themselves.Got it much faster! I ordered 2 and i though they send me one but it was 2 in the package my bad. They are thick, The only thing it is NOT the same color like on the picture i wanted darker solid grey so they don't let light in, but they are light grey, quality is amazing for the price just the colorI love these panels. The color is beautiful and they are true to size. I've purchased panels in the past that have been uneven when you actually put them up and that's not the case with these panels. I purchased the light gray and they are true to color matching the picture! The seller was great to work with as well and response to emails quickly!I bought these curtains in black hoping for a great buy. They were not near as wide as you think they are. Buyer beware make sure to purchase at least two if not four of these to cover a normal size window. Didn't block out much light either. Didn't bother returning them though because they sent me the wrong color of the other set of curtains I ordered and it was a hassle. They charge you to ship them back even if it's their mistake. I wouldn't work with them again. Good luck to anyone else who orders. I'd rather pay double the price or more to get good quality real black out curtains than purchase from them again.
