- Complete Blackout: Tired of Light Pollution Disrupting Your Sleep? Our magnetic blackout window film made from premium 420D Oxford fabric (Polyester) that is resistant to wear and tear, achieves complete darkness with our blackout curtains for better sleep, home theaters, or any other use where total light blocking is required.
- Magnetic Installation: Easy to install with no-trace adhesive-backed magnets, allowing for quick and tool-less setup. Simply attach the magnets to your window frame and align the curtain's iron pieces. Once you no longer need black out, the no-trace adhesive-backed magnets ensure that there is no annoying marks on your window frame.
- Thermal Insulation: Maintain your indoor temperature by reducing direct sunlight. Our room darkening window film blocks out all external light, significantly lowering room temperature by preventing sunlight from entering your space, keeping it cooler in summer, and helping reduce cooling costs in a busy city.
- DIY Customization: Easily cut or fold the blackout blinds to fit any window shape or size, providing a perfect custom fit for your needs. Ideal for bedrooms, nurseries, offices, home theaters, and any other space where you need to block out light and maintain privacy.The color of the product are black-silver instead of black-white.
- Our blackout window cover is primarily made from polyester, capable of blocking 100% of UV rays. However, the thickness is less than traditional curtains and may have fold creases which may result in a slight decrease in interior aesthetics. If you are concerned about aesthetics while needing blackout effects, it is recommended to use our product in conjunction with traditional curtains.

I bought this product because I had tried several different “blackout” curtains in my daughter’s nursery that still didn’t leave the room actually dark enough for her to take good naps. Even the “100% blackout” curtains let in a ton of light. Before I had kids I worked night shift as a nurse and I remember literally taping black poster board over my windows to make the room get dark enough for me to sleep well, and it worked really good but I didn’t want to do that in her nursery because I like being able to have the daylight in between her naps while she plays on her mat and does tummy time. So, this was my solution—it basically functions the same as the posterboard, except you can put it up and take it down at your leisure and it’s super easy. The kit comes with adhesive magnets that stick very well to the window frame as well as magnets for the “curtain” itself that also have a good, strong adhesive. The material is thin but that doesn’t affect its ability to darken the room. One side of the material is black and the other side almost looks like aluminum foil which also helps keep heat out (think of it like those panels you see people put in their cars during the summer to deflect heat) which was another issue we were having in her nursery as it was getting too hot during the day from sunlight exposure. My only real “con” is that the initial setup is definitely a two person job especially if your windows are large and you are short like I am. Once you get the magnet placement the way you want it, though, it’s very easy to take them down and put them back up on your own. The images in my review show the window before the panel was put up, with just the panel, and then with the panel and blackout curtains combined (best result).

I purchased this blackout vinyl for my bedroom windows, and I couldn’t be more pleased with the results. Installation was quick and straightforward — just cut to size, peel, and stick. The adhesive is strong but removable, so there’s no damage to the window if you need to reposition or remove it. The blackout effect is fantastic. It completely blocks out sunlight, which has drastically improved my sleep quality. It’s especially great for night shift workers or anyone sensitive to early morning light. I also noticed a noticeable improvement in temperature control — the room stays cooler during the day by keeping the sun out.

Impressive Blackout Solution – Almost Perfect I’ve been using the BKSAI Cuttable Blackout Window Covers for a few weeks now, and overall, I’m really pleased with how well they perform. I was searching for a flexible, non-permanent blackout solution for my bedroom and office, and this product mostly delivers on what it promises. One of the standout features is that the material is cuttable, which made it easy to customize the covers to fit my unique window sizes. I appreciated how straightforward the process was—just measure, cut, and stick. The blackout material is thick and effective. Once installed, it made a noticeable difference in blocking sunlight and even helped with temperature control, which was a pleasant surprise. My room stays cooler during the day, and the light reduction has significantly improved my sleep quality. The design is sleek and minimal, and the black color adds a clean, modern look. These covers are especially great for renters or anyone who doesn’t want to install permanent blackout curtains or shades. They’re easy to remove and don’t leave any marks or residue behind, which is a big plus. The only reason I’m not giving 5 stars is due to the adhesive backing. While it holds well for the most part, I noticed that a couple of corners started peeling after about a week. I had to reinforce them with some additional tape to keep them secure. It’s not a dealbreaker, but it’s something to be aware of if you’re planning on using these long-term or in a room with high humidity or heat exposure. All things considered, the BKSAI Cuttable Blackout Window Covers are a great value and a smart solution for anyone looking for a customizable way to block out light without breaking the bank. With slightly improved adhesive, this would easily be a 5-star product.

The shade itself works great. There is no light coming through the window & it helps keep the room cooler, that deserves 10 stars. The only reason I give it 3 stars is because it doesn’t stay up. The sticky part on the discs doesn’t last very long on a window that gets very hot. I’ve tried using multiple discs & magnets and have tried sticking them on various parts of the window & window frame but the shade continues to fall.

The magnets and the hook and loop strips were fine. The cloth was awful. As soon as I opened the bag with the cloth, I was hit with a very strong, fishy smell. A smell that reminded me of sardines. I tried to see if it airing it out would help, but it just made the smell stand out even more. The smell just made it unusable for me. In fact, the smell was so bad that I just threw it out instead of returning it. I just couldn't stand it. It's possible that I got unlucky and that most of the other items in this product line smell fine. I don't know, but this experience has forever ruined this company for me. Never gonna purchase from this company ever again.
