VELIMAX White Blackout Window Film, 100% Light Blocking Window Cover, Opaque Vinyl Cling, Privacy Film for Glass, Sun Blocking Films Non Adhesive, 17.7in x 78.7in

Used this to blackout 2 sliding glass doors and 2 fairly large windows. I work night shifts sometimes and this is a godsend. I sleep a lot better with my windows blacked out and am able to take really great naps during the day as well. If you follow the instructions, use common sense, and have a little patience this is really easy to do. I'm not sure what all the negative reviews are about, it just takes a little time and following instructions. Watch a you tube video. Measure your window, and order a size roll that closely resembles the size of window you are trying to black out. A little math and you may even be able to do 2 windows with 1 roll. It stretches and sticks pretty easily once it's on the window. Also go ahead and buy a couple new utility/razor blades because it makes it a lot easier if you have a very sharp knife. Trust me, have a few new utility blades on hand. Spray plenty of water on the window after you clean it and use a credit card to help you cut straight edges along the window. You will probably have a tiny tiny bit of light peeking in along some of the edges but it is hard to get rid of all of it. If you are OCD you can probably negate a lot of it but this product will eliminate 99% of the light from the room. One thing about this product I like also is that it doesn't look terrible from the outside. Once you have it installed go outside and look to see where any extra air/water pockets are. After you have it cut and put onto the window it's easy to peel off if you don't want the room blacked out, and then you can reapply without cutting anything again.

Worked perfectly. Clung to the windows with just a spray of water underneath. Super simple to apply. Easy to trim to size. No light is visible through the film. Perfect solution for babies who need to nap or privacy from nosey neighbors. The black was pure black with a texture to make it thick and light proof.

This works well enough. Applied it to a 20”x 20” square, east-facing, bedroom window. It was impossible to sleep in there beyond sunrise even with a shade. That window also works as a dang radiator; that room is always hotter than others. The film can be a little finicky during application; it slips and slides if you’re not careful, but it gets the job done. Unfortunately, I was unable to cut off the excess along the edges because I don’t have a tool sharp enough to do so. It needs to be Xacto-knife sharp. All of our box cutters and such are far too dull. The film just slides around when attempting to cut it. So I just left it. Aside from that, I’m pleased. It’ll be hidden behind the shade anyway. It truly is 100% blackout as long as you manage to cover every square inch of the window. Any and all gaps, no matter how small, will be very noticeable though so keep that in mind if you don’t plan on covering the window with an additional curtain or shade. It certainly makes the room cooler and much easier to sleep in. Great, budget-friendly fix.

"Amazing quality! I was looking for something that would truly block out all the light so I could sleep better, and this blackout film exceeded my expectations. The grid on the back helps so much with measuring and getting a precise cut. It adheres perfectly and leaves a clean finish. Definitely 5 stars!"

Not sure about the other reviews but glad I took a chance to purchase, will be buying another roll! Very easy to cut with guidelines and much thicker than window cling I've used previously. Backing wasn't terrible to remove just some effort (initial piece has removal tab, second piece after cutting didn't but wasn't too difficult). Application was very easy, cleaned the windows then sprayed with water and used a card to squeegee out any bubbles. Stuck very firmly. Went with white knowing black isn't for double paned windows. Last summer I used white foam board which worked well to block out sun/heat but due to thickness need removal every time I wanted to open the windows. This is much more efficient for about the same cost. Some reviews complain it's not completely black out, which is not true. The cling itself is completely black out but due to caulking at window/glass seams it's not possible to get true edge to edge coverage. Easily remedied with some white electrical tape over these edges.

Bought the black film and was a quick and easy install. Only to find out that risks breaking double insulated windows. Should've checked my windows before buying black. I'll have to buy white film now.

This tint is perfect for the windows in my house keeps the sun out tremendously and makes my bedroom so much darker in the morning helps keep the electric bill down yay. Seriously great deal.

I originally bought the black one because the white one didn't exist (2018) and I had to write a review asking to have a white one made because white repels heat better than black (white reflects light). The stuff from 2018 really stuck to the window and I didn't have to adjust it in the slightest bit. So I then bought the white one after a number of years (2024) but I was so busy that I didn't get to install it until this week. With that I wanted to share a few tricks to get it to stick: - The soapy water trick really does work. 2-3 drops of normal soap in a spray bottle and it really sticks. Not sure about Windex which typically doesn't have soap but alcohol and ammonia. The soap dries on the window surface and adheres to the plastic. Then it doesn't budge. Not sure if the lower rated ones failed to spray with soapy water or not Manufacturer says to use soapy water. - If it's gong to be a hot day it tends to work better than a cool/cold day. This is because the water from the soapy water evaporates faster and thus the soap from the water makes it stay in place really well. I had hell trying to get it to stick on colder days. The windows in my tiny apartment can melt the adhesive on duct tape, which is likely why it adhered well. Not sure if a hair dryer would help or hinder. Maybe low? Be careful of melting the plastic though. - On windows that DO NOT move, it's better to cut it a little larger than the window if you want to really block out all of the light. On windows that do move, I read that electrical tape works... I tried that and it kinda does, but as I said, the adhesive on tape tends to melt on these windows. (They are not double insulated or anything. They are single pane windows.) In the end it worked well for my steamy top floor apartment and has not peeled. It did cool my apartment like I wanted. I used the white frosted version to let in natural light on some of the top windows.

Followed instructions and it is hopeless

it is very good but bit over priced according to size

Waste of money! The product came with holes on it and it is not at all black out!!! The light still comes through and it also doesn’t stick well on the window! Literally waste of money!

I put this up in my room and my toddlers room. Mine has been up almost 2 years, and other than peeling back a bit at the corners, it's stayed up very well. In my toddlers room I took it down at winter and put it back up once the days got longer again and there were no issues with it staying up, it was like new, really pleased.

muy bueno, totalmente opaco, no deja entrar nada de luz, justo lo que queria.
