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!

Do Not Recommend, More Aggravating than helpful
This was not worth the price. Sure it’s blackout and reflects the sun away from the room, but it is very difficult to put up and took more than one person to cut, shape, and put on the window. And there is still too much light coming through. I would not recommend this for anyone. I ended up using gorilla tape in order to hold it to the sill and try to cover the lower part of my window.
