A Total Game-Changer! Achieving True Darkness Has Never Been Easier (Or More Perfect!)

I rarely take the time to write reviews this long, but the 100% Blackout Curtains for Bedroom (118" x 57" Portable Window Blinds Cover Adhesive) deserves every single word of praise. I am absolutely blown away by this product. If you are struggling with light bleed, if you are a shift worker, or if you simply crave a cave-like sleeping environment, stop looking right now. This is the solution you need. It worked perfect from the moment I put it up, and honestly, the results exceeded even my highest expectations.The Pursuit of Total Darkness: AchievedLet's talk about the key selling point: total darkness. I’m talking about pitch black. The kind of darkness where you hold your hand an inch from your face and cannot see a thing. Before finding this product, I had tried everything. I layered heavy velvet drapes, installed room-darkening blinds, and even attempted to tape heavy-duty aluminum foil over problematic window gaps—all to no avail. There was always that annoying sliver of morning sun around the edges, or the glow of a nearby streetlamp cutting into my sleep.These adhesive blackout curtains truly deliver 100% blackout. The material is thick, robust, and completely opaque, but the real magic is the adhesive element. Because it can be mounted directly to the window frame (or even directly onto the glass, depending on your setup), it creates an impenetrable seal. There are no gaps for light to escape, period. My bedroom is now an absolute sanctuary, completely isolated from the rising sun. My sleep quality has improved dramatically since installing this.Installation: Easy, But Precision is KeyI was initially nervous about installation, especially with such a large piece of material (118" x 57"), but it was genuinely easy to install. The material is flexible and manageable, and the adhesive backing is strong but also forgiving enough if you need a slight adjustment before applying final pressure. It’s essentially peel-and-stick, but on a grand scale. No complicated hardware, no drilling, no struggling with cumbersome curtain rods. You just need a pair of sharp scissors or a box cutter, a ruler, and a little patience.This brings me to the single most important piece of advice, which the seller wisely mentioned: Measure twice before cutting. This curtain is large enough to cover substantial windows or multiple smaller ones, so you have plenty of room for error—but you only get one chance to make the final cut. Take your time. Lay the material out, measure the exact dimensions of the glass/frame you want to cover, mark it clearly, and then cut with confidence. Because the installation is so simple otherwise, spending the extra five minutes on precise measurement will ensure your final result is flawless and light-tight.Portability, Versatility, and Unbeatable ValueWhat makes this product truly innovative is its portability. While I installed it semi-permanently on my bedroom window, the fact that this is a portable window blinds cover makes it indispensable for so many other uses. Moving into a temporary space? Traveling to visit family? Need a quick solution for a guest room or a rental apartment where you can’t make permanent changes? This adhesive blackout cover is perfect.The huge dimensions (118" x 57") also mean you get incredible value. It’s not just a bedroom solution; it’s an ideal product for:Home Theater: Eliminate glare and light in a TV room for the ultimate movie experience.Baby Nurseries: Ensure consistent darkness for nap time, regardless of the sun’s position.Home Offices: Block out distracting glare on monitors.In conclusion, this product delivers exactly what it promises: 100% blackout with a supremely easy to install adhesive design. It is effective, versatile, and high-quality. If you need darkness, you need this. Five stars without a single reservation!

Works Fantastic - Not Much Of A Thermal Barrier Though

Disclaimer I received this product for free via Amazon's Vine Program.I was unfortunate enough to work night shifts for awhile and needed to swap out my window blackout curtains with something nicer that fully blocked out light versus just darkening the room. Figured I'd pick these up for review.First off, the privacy and light blocking abilities are fantastic, definitely 100% light blockage and I don't see anyone complaining about that. Installation is very easy with pre-included adhesive velcro tapes.The quality of the panels is nice and very lightweight, I'd say the closest thing material wise would be a mylar blanket (although these are much thicker)You also get a very large amount of coverage for the price, which makes these an excellent value.Would recommend!

Very nice and easy to use

This works great! I love that I can cut it to the size of my window also! It stays put and blocks the draft from the window and gives privacy. It is as advertised and works great.

Dorm room approved

Works GREAT, i got these for my dorm room and they litterly transform the room. We have these useless blinds and an annoying street lamp right out side our window. I just measured the window and cut it to size, threw it up and WOW they actually made it pitch black. (Which was a double edged sword bc then in the morning it made you never want to get up lol)It lost a star because while the glue dots are great and still going strong by the end of the semester, the velcro gave out awhile ago. The sticky part that keeps it on the window like... melted? I guess the sun heats the window but like... shouldnt it be able to withstand that if its supposed to be on the window? Honestly i dont mind that much, for a little while we just kept pressing them back on at night and it would hold for a bit then fall off at some point during the night. Now theyve lost all stickyness *shrug* just use the glue dots, they work great and the blackout effect is fantastic.

Great product for an even better price!

Worked perfectly in my guest room when I had my niece & nephew visiting. Easy install, and it truly blacked out the window. It’s lightweight so I didn’t to use too much Velcro (came with the curtain) to secure it properly on the window.
