Blackout Curtains for Bedroom, Portable 100% Black Out Window Cover Film, Cuttable Blackout Shades Fabric Sheet, No Drill Window Blinds, Sun Heat Light Blocker for Travel Media Dorm, 57'' W

This was much easier to install than the static cling alternative and more effective than curtains since it covers the whole window and reflects more light. My picture shows regular blackout curtains on the left and this product on the right - covering the smaller window. Just covering the two small windows in that room helped cool it down a bit. My only problem was not being able to iron out the creases but that didn't affect it anyway since I pulled it right when sticking it to the dots on the wall. It would have been a bit easier to measure precisely if I could have made it totally flat but that didn't seem worth taking off a star, especially since it maybe possible but I was too nervous to increase the heat on my iron past the very low "synthetics" setting. I was impressed by how easy it was to cut without damaging this very thin fabric. It didn't fray at all when I used scissors, exacto knife, or a sliding paper cutter. The dots are very sticky but I was able to reposition the one that I accidentally put on the painted wall in the wrong place (without damage to wall or loss of adhesive power). The Velcro also sticks to each other very tight and seems to be high quality. I have not tried using the other adhesive dots yet.

Has so many uses. I get really bad migraines. I have tried so many different black out curtains, drapes etc THEY DON'T WORK. I can't have any lights. With most products you are going to get a line across the top or sides that lets in light. But NOT with this stuff. I can Cut it to ANY size or shape I need. It comes with a Velcro set-up that takes seconds to turn a bright room to feeling as if you're underground. The Velcro makes moving it, or pulling up 1 side so EASY

The material itself is 100% blackout, but you won't get 100% blackout in your room with the included mounting velcro dots. There will be some light leak around the edges. They still block the majority of the light and a bit of heat in rooms with major sun exposure, though. Even with prep I still have sections where the adhesive didn't stick well to the glass and corners of the curtain will fall down. A fresh piece of velcro fixes the issue, at least for a while.

These have made a big difference in blocking light from the windows. One side is silver, other side is black. It cuts very easily and supplied a lot of double sided hook and loop stickers. The stickers are very strong. I used these for night shift work and supplemented with "black out curtains" they are really make it near 0% light transmission. The only spot is around the edges if you don't use enough stickers.

Update!!! I'm not removing my first review just updating after a few weeks of use. I'd say the material is nice and it does black out the window. It keeps some heat out of the house but the area around the window is still quite warm! Does it reflect heat I'm not really feeling as though it does. I feel like I could put an emergency blanket up there for better heat reflection than this. Not to mention they sent a stapler to staple the velcro on the corners BUT this doesn't work... it's not just the velcro that sticks to the material it's also the one that sticks to the frame of the window. The corners fall all the time.... the velcro is worthless and i am going to have to improvise with some command straps. I don't want to use the non removable white sticky dots sent because I don't want to have to go through the pain to scrape them off. I'm taking 2 stars off my original 5 star review for quality and in ability to keep heat out. All in all I kinda feel like I wasted money. Ok hear me out, I live in sothern California further east away from the beach... it gets HOT here in the summer and our AC can't hack it. I tinted my bedroom window and my sliding glass door because those don't recieve direct sun all day long. My dining room and living room windows are on the same wall where they both get blasted by the sun. I haven't seen how well it keeps the heat out just yet but I can say it's easy to install!! I may make a modification by sewing the velcro pads on to the fabric as yes they don't stick well to it when trying to remove the fabric from the window during the evening time. I may also eventually change the velcro altogether with long thin strips rather than the dots so it's a consistent strip. All in all I'm happy.

Makes a room SO dark and helps with temperature regulation. Also super easy to put up.

I bought supposed black out curtains from a dept store that stated they were blackout. After hanging them, they were so sheer i could see people on the other side of the window. I LOVE this. I have odd windows in my bedroom and get up at 4 am for work and in the summer it's light till 9:30 pm. Not only are my windows odd shape, I also have a window air conditioner. This came in big sheets. After I laid it all out and measured the window I cut out the pieces I need to fit around the air-conditioning and the odd shaped window. They supply a stapler for you and velcro. The stapler is to staple the velcro to the curtain. So smart as the sticky velcro did not work on cloth. The reason I choose to try this item, is because of the test in the video. They turned on the flashlight on their phone and we all know thats pretty bright and saw nothing so I gave it a try and am so happy I did. My bedroom is pitch dark in the middle of the day. I go to bed at 7 pm and even my dogs come with me, thinking it's night. The window faces south so it gets sun all day and heat and the velcro hasn't budged. Why didn't I do this the first time. These are amazing at blacking out all light. And tge price is amazing. I would give 10 stars if I could.
