    • I used it for summer and winter weather.
Number of Items: 2 Color: White Size: 40"W x 84"L (Pack of 2)
These are the best curtains. It block the lights, it block outside heat from entering during these heat wave. It’s to me thick enough for my liking.

Just what we were looking for a student apartment. Super soft fabric, light weight but excelent coverege, wanted for privacy at night and does the work! It has double fabric, the back of the curtain is white (which contributes to the coverage). It took us a while to decide which courtain was the perfect one for us since we had few requirements: it had to be affordable, with good night time coverage, preferably with no hooks, no ruffles, easy tu run, light weight (the rod does not support too much weight), not too bright color - and we found them all in this one! Also, the fact that there are two options to hang the courtain by the way it is made at the top (not sure how to explait it, see pics) was a plus - we just went with the way it seemed more easy to run. We got the navy blue color and in fact it is a rich dark matte blue navy.. loved it! PS. Probbably two courtains would have looked better for the 42" window, but one does the job for now. Cons: it comes wrinkled (folding marks) but what folded fabric/courtain doesn't. They are fading away with time. No comments on its insulation or energy saving effectiveness (it was not a requierement for us). ... show more

    • RECOMMENDED,especially at this price for 2! Amazing deal & great quality of blackout curtain panels!
Number of Items: 2 Color: Olive Green Size: 40"W x 84"L (Pack of 2)
Why did you pick this product vs others?: YES, RECOMMENDED. I was completely surprised by the quality and effectiveness of this product, especially for the price for the 2 panels! This was an outstanding value for this item and worked perfectly for blocking out the sun rays and ambient heat at the window. The color was subtle, but pleasing. I would not hesitate from recommending this product, especially at this price! ... show more

    • 100% Blackout
Number of Items: 2 Color: White Size: 40"W x 84"L (Pack of 2)
These work great for blocking out sunlight. The material feels a little cheap, but for the price point, it’s a great deal. The white is kinda sterile; I’d prefer something a little less “hospital curtain” looking. But the main purpose was to shield us from the early morning sun and these curtains work 100% at that. ... show more

    • DEFINITELY WILL BE BUYING MORE!
I really like these curtains. I bought these for my daughter's room to go with her color scheme & to keep out some light. They are thick & of great quality. I think I did buy them a little too long but it's fine. They look really good.

    • Chemical smell
Number of Items: 2 Color: Stone Beige Size: 40"W x 63"L (Pack of 2)
The chemical smell would not go away. It got worse when the sun heated them up. I tried washing them several times and leaving them to air out on the porch. Still stunk. I ended up taking them all down.

    • Varying panel sizes - Wash twice before installing!
Number of Items: 1 Color: Blush Pink Size: 40"W x 63"L (Pack of 1)
I ordered 24 of the same panel, and some of the panels were significantly shorter than others (by a couple of inches!). One of the panels had small holes in the blackout layer that caused pinpricks of light to bleed through it. If that's what you're going for, it makes it look like starlight almost, but I wanted BLACKOUT. Aside from the damage to one and the odd lengths, the panels do what they say they do: 100% blackout. I've not had any issues with light bleeding through the blackout layer except where the blackout layer was damaged. I recommend washing, drying, and rewashing these before putting them on your windows. The wrinkles do not want to come out of the curtains until the blackout layer has been thoroughly delinted, and they have a strange smell that does not want to go away until they've been washed a couple of times. I tried a single wash that definitely threw a lot of white lint into the trap during drying, but the smell remained until after the second wash. ... show more
