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.

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.

I like this product this was an alternative to purchasing big custom curtains/shades, with the heat here in Las Vegas it helps with blocking out most of the heat, install you have to be patient and iron out as much as you can (careful not too hot) but make sure you measure the desired areas before cutting. With cutting i found the edges to be fraying but that could be just the blade but overall good product.

Genuinely works amazingly. Entirely blocks light and was pretty simple to install

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.

This is absolutely been a game changer for me! I recently started working third shift and I was not able to sleep during the day because my blinds could not block out all the sunlight. Upon buying this, I have been able to sleep during the day wonderfully. The only thing that I can find to complain about is that the sticky side for the Velcro stickers are not that great after it’s been used a couple of times.

Arrived as expected. Packaged well. Instruction included, as well as all items needed to determine size needed. You will need a pair of scissors to cut after you have measured the area needing covering. I struggled a little to separate the double sided dots/tape. But once done they worked fine to hold the material to the window border. it does help prevent the house from getting as warm as it might. Light blocking is 100%. I have plenty of material (I ordered the two pack) and necessary items to secure to border of window.
