Little to no light bleed with some help
Good for the price.I have "hanging blackout curtains" with these "velcro curtains" underneath them to prevent daylight, and light spill. It works great, though you will need to staple the velcro onto the sheet to keep it from pealing off.There 1st picture is what it looks like with 5 pm, full strength, Texas-setting-sun hitting the window directly. The 2nd picture shows what is outside my window at night; a tremendous amount of light pollution. The 3rd picture is what it looks like with without the "hanging curtain" drawn at night. With the "hanging curtain" drawn, there is no light bleed.

My Sleep Sanctuary—Thanks to Sumobaby!
I never realized how much light was disrupting my sleep until I tried the Sumobaby 50”x57” Portable Blackout Curtains. From the moment I installed them, my bedroom transformed into a peaceful, pitch-black haven.The installation was a breeze with the included hook and loop tapes. I was able to cut the curtains to perfectly fit my window, ensuring no light seeped through. The high-density black polyester fabric, combined with the reflective silver coating, truly delivers on the 100% blackout promise.   Not only has my sleep quality improved, but my room also stays cooler during the day, and I enjoy enhanced privacy. The curtains are lightweight yet durable, and their portability means I can take them with me when traveling.If you’re seeking an affordable, effective solution to block out light and create a restful environment, I can’t recommend the Sumobaby Portable Blackout Curtains enough. They’ve made a world of difference in my daily life!

Great for privacy
WORKS GREAT! Super easy to cut and size and completely blocks out the light! For the price it’s pretty worth it if your looking for darkness or a bit of privacy especially in an apartment

Gets the job done. I’d say 80% darkness.
They get the job done. We still are not able to achieve total darkness but in the middle of an Alaskan summer we appreciate anything that gets the room a little darker. We have them underneath blackout curtains and a little bit of light still seeps through the top and sides but overall it has still made a huge difference for us.It was easy enough to set up but decided to just use little tacks to hang it as the Velcro wasn’t sticking well to our windowsill.All in all I think this is a great product for the expectations I had set for it. If you’re looking to achieve total darkness though this might not do the job.

Great for privacy!
I bought these because my blinds stick out of the window frame by over an inch. If I have my lights on at night, people can see inside. And I have neighbors that point cameras at all my windows.I put one way privacy film by Gila on my windows for daytime, and these shades at night.I turned my lights on low, with a lightbulb that is controlled by an app, and has a dial for light brightness and color. I walked outside and was surprised my windows looked like my window tint during the day-black. I had put the shades over the white blinds, so I thought I would see the white blinds. No, just the window tint.However, I did put black electrical tape around the frame of the shades. My frames are not flat. They curve inward toward the window, so when I was using just the velcro, light would peek in from the sides. So I put the tape around it. The windows I do open up during the day, I be careful when lifting up the shades and smooth it back down at night. I have tape on hand for touch ups as needed.I tried duct tape, black electrical. The duct tape pulled off some paint and wallpaper. The black wide electrical tape didn’t. I bought some of Amazon that were 2 inches wide. I think. I tried a less wide one from amazon, but it would tart to curl up. To put the shades up, I had the shades down, and I put two velcro pieces on top of it. Then the other side of those two pieces, I put it up higher on my window frame or the shade itself. So when I open up my blinds I don’t have to take off the entire shade. I just attach the lower part of the shade to the top of my window frame or shade, using velcro. Since I am just folding up the lower portion, the tape around the top remains intact. I don’t usually need touch ups.I did try the velcro that other people have bought separately and used, but when I removed the velcro completely from the window frame, it pulled of the paint-the sticky side. So I just use the included ones they give. Not as sticky, but no damage. I contacted them and they gave me more velcro within 2 days.Some of my shades are turned black outward, others silver outward. I put them over my blinds, but since I have window tint, all my windows look black,They don’t see my blinds, which are white. People can’t see in at all. They just see black. That was my main concern. I didn’t want people looking in at night. I would completely recommend this product for privacy.

Returned due to size
I had to return these because they didn’t fit, but I will say they seemed easy to put up and the return process was quite simple.

Works better than I thought
Amazing! This is a great option if you have too much sun coming in the windows. I've never used this type of product but I'm impressed.I moved into a house in southern California with no insulation and the sun blasts through the living room windows. I waited until today to leave this review because the high is 94 today. Usually by this time (86 degrees) my house is hotter then outside, even when I keep my regular shades down. When you pass the windows, you can feel heat then it gets trapped in my house.Not today! We cut it to fit directly on the glass so we can still open the windows on cool days. 86 outside right now, my house is usually about 90 degrees by now. Since it's going to be hot today I shut all of the windows and shades in the morning before the heat came through, I have 1 side window in the shade that I opened and put a fan in and with this reflective window cover my house is only adding 73 degrees instead of 90. Sturdy material. The velcro works great, sleek black color really helps keep the room cool. Easy to use and worth every penny!
