KESPEN Window Privacy Film One Way Daytime Privacy Static Cling Sun Blocking Anti UV Reflective Window Tint for Home and Office, Blue-Silver, 17.5 Inch X 6.5 Feet

Well, I just want to say this stuff is fantastic. It's super thick vinyl, not like the cheap crap you get for your car. It also reflects light pretty dang good. If you look at my pictures, there is one where you can see the blinds on the left. That is the only window I couldn't complete on my whole house (in pictures) with the 35.4" x 32.8' roll. However, if you look closely, it is also the only one that you can see the blinds through. That alone should tell you this crap works. I live in an area that gets to about 200*F on a cool winter afternoon, and the front of my house heats up like a smelting furnace. My power bill, is, well, astronimcal. And that is just so I can wake up in the morning without wet sweaty sheets. My kitchen, in the afternoon, is like he*l's inferno, and Satan himself would be asking to go back home if he had to stand in front of one of the windows. LUCKILY, after installing these on the first window in my kitchen, it instantly felt about 10 degrees cooler. I couldn't feel the sun beating through anymore. By the way, I have 2" thick vinyl blinds on every window, and they only help so much. Anyway, after finishing the front of the house, I came home the next afternoon and my house felt MUCH cooler, so I did the back of the house. My bedroom no longer gets sunlight in the morning to wake me up through the blinds, and I love it. I totally recommend.Now, to the good stuff. I have never used tint before, so know this:1. Buy a window tint kit. Make sure you get one with a straight edge razor, a squeegee with the cloth wrapping, and a regular window squeegee. I purchased this one for 10 buckaroos: https://www.amazon.com/dp/B01J3QVS2K?psc=1&ref=ppx_yo2ov_dt_b_product_details2. Buy a metal meter stick from harbor freight or walmart, because you will need it to measure your cuts as well as to use as a guide for cutting. Also, buy a medium sharpee to mark the areas as well. When I made my cuts, I set it down on a flat hard substrate that I didn't mind gouging, and I set the meter stick to the marks I made and sliced down the meter stick, using it as a guide.3. It is better to cut your squares a little big than a little small. You can always use a ruler or a squeegee to mash the tint to the edge of the window, and run a razor down the crease. If you are cutting excess out in the window frame, which you will most likely do, I used a metal ruler to guide my razor, because it is virtually impossible to keep a straight line if you do not use a straight object as a guide to run your razor down.4. The directions show a bottle for soapy water. Throw the directions out. I found that a big a$$ mixing bowl with a 50/50 dawn dish soap and water solution works just great after screwing around with my first two windows. I used a micro fiber cloth, wet the window generously with my dawn solution, and then stuck my tint to it. Then if the tint doesn't slide easy, as in no effort used, then take it off, and reapply a generous amount of solution. That will do the trick, as now the tint is already soapy, and now the window is now soapy.**** Did I mention you need your glass spotless? Cuz' you do. If you don't, your little cat or dog hairs or boogers will show up under the tint. Use the soapy solution you make, and scrub with a micro fiber, and then use the squeegee you buy to swipe the window clean!!!6. Once you tint is in place, ALWAYS WET THE BACK OF IT GENEROUSLY, because this stuff will stretch and contort and malform itself. If you keep the back of it slippery, your squegee will move easily without scratching it or stretching it.7. Do not press hard. Use light pressure, as you will scratch it or stretch it.5. DO NOT USE A HEAT GUN YOU DO NOT NEED IT DO NOT USE A HEAT GUN YOU WILL DESTROY YOUR VINYL. ASK ME HOW I KNOW.6. Once you have it squeegeed into place, you can start cutting the excess millimeters off to make it fit correctly. USE YOUR RULER AS A GUIDE!!!!7. You need some small gaps in order for the soapy water and air to escape, so even a small amount of gap between the window frame and tint doesn't matter. It still blocks light just as good.8. Once you are down, you can wipe 'er down. Come back in a few hours, and you will be able to see where all bubbles are that you missed. In my case, it was the next day, and they don't look like bubbles as much as baby swirls, which is water trapped under. I just made another batch of dawn solution, wiped down the back of tint with it, and squeegeed the rest of the bubbles out!9. Enjoy your nice dark and cool area!That's my review of this, as I reallly appreciate how well it seems to be working. I'm excited to see how much my power bill drops, because even if it's only 10 bucks a month, this stuff pays for itself in less than a year. I'll be back to update.UPDATE: My first power bill was down $60. 2 months of that in the summer pays for all of the materials. The house has been noticeably cooler as well.

This window film is perfect for living in apartments or living close to neighbors. We have two cats that love looking outside, but it unfortunately invites a lot of unwanted attention from all of the kids playing outside. They frequently were pressing their faces up against the window and banging on the glass whenever they would see the cats sitting in the window. We decided the only solution was to cover the bottom part of our living room window with this reflective film.As long as you have a spray bottle of soapy water, a squeegee (or a credit card wrapped in a towel works the same) and an exacto knife, then it is super easy to install the window film with no air bubbles. I would recommend watching a tutorial video on YouTube for best results. One thing to note is there are two sides to the film and one is subtly more reflective. When installing make sure you place the more reflective side facing the outside. Those who are complaining about the reflectiveness at night time or the film not working I assume have installed it incorrectly. The film is thick which makes it easy for installation without professional help.We bought the black-silver film and it provides full privacy during daylight hours, even up to 30 minutes before sunset. Not a single person sees our cats from the outside anymore and they can now peacefully sit at the window without being disturbed. If you buy this, you will not be disappointed. Just make sure you buy the right size film for the area you plan to cover and expect that it will change the inside lighting a bit. This film does not provide privacy during the night time and you still need to use your shades/blinds at night. 100% would purchase again and we plan to use this for other windows.

I live in Alaska, just 100 miles south of the Arctic Circle, in the Land of the Midnight Sun. I've tried several different products to darken my room enough to sleep well with different degrees of effectiveness. I was very excited to see this product and surprised that it worked so well. I get nearly 100% light blockage from this film. Unfortunately, it hasn't stayed firmly attached and I needed to use tape to hold it up. But, I'd still buy it again because it works well and was much easier and more esthetically pleasing than the other things I'd tried.
