BDF S15 Window Film Daytime Privacy and Heat Control Mirror Silver 15 (Dark) - 36in X 50ft

I watched the video twice and followed all directions, spraying water on both sides before adhering. Still, like the others describe and after doing all of this preparation very carefully, we still have quite a few small bubbles/pulls/lifts which are very visible from the outside. From the inside it looks fine but close up from the outside the mirrored side looks terrible. The process for installation is not hard. I believe the problem is that the film is too thin. If the film were thicker, it would lay better and the bubbles would resolve without ripping the film. Regardless I love the way it turned out on our shower door. I would use it everywhere if it was possible to eliminate the bubbles. I found the squeegee included with the kit super handy and obviously required however if I were to do a bunch of windows I would buy a much larger squeegee

Installing this stuff is a pain. However, the amount of heat rejected is awesome.Only downside is the window will have a very silvery/mirror look to it from outside during daytime.I had one room that would struggle in late afternoon, and would crawl up into the 80s, despite rest of house being 71.Since installing this on 3 doublehung large windows, room has stayed constant with rest of house.

This product is CHEAPLY MADE. I used a different brand previously, and now I am regretting not using the prior brand. The previuusly used brand was a 35 and this brand is a 15%. The previous brand is much darker then this brand and it is suppose to be much darker (only in their dreams). It ripped quite easily when you were trying to cut it with the cutter and also they enclosed a plastic tool for smoothing out the bubbles that was hard plastic on one side and covered with a material of some sort on the other. BOTH sides scratched the film even using a gentle touch and using it correctly. The dry film is cloudy from the soapy water (baby shampoo). so very disappointed in this product, do not recommend.

Overall I would recommend this film as I live in a house that was suffering from huge single-pane, east-facing, rear-sliding door that soaks up a lot of early day southern California heat and makes it difficult to keep the house cool. Once the film was applied there was a noticeable difference in the temperature and glare. The outside is like a mirror during the day, and then when it gets dark the effect is reversed and the inside is a mirror. The main drawback, and I don't consider it major because our overwhelming concern was heat/glare reduction, is that if you are very particular about it looking clean and smooth and perfect, you are almost certainly going to be disappointed, because it is very difficult to apply without any bubbles/wrinkles/pulls/lifted corners, especially the larger surface you are covering. And since mostly people with single pane windows are going to be ordering this product, it means the windows are probably older and not in the best maintenance. NOTE: PREPARE THE WINDOW! Take a razor blade to the entire window to remove paint droplets, grime, residue and anything else that may have stuck to the window over the years, pay attention to the corners. Then clean the window twice to make sure the surface is a clean and smooth and flat as possible. This step is crucial to getting a better application.The squeegee they pack with it should be twice as large to help speed the process (which is important because you have to get the film applied in a relatively short amount of time or the soap solution starts to dry and makes it difficult to remove bubbles/pulls). As with most of the other reviews, I can't recommend enough to spray, spray, spray lots of the soapy water solution before AND during application on the window, on the adhesive side of the film, and the other side of the film as you are applying and squeegeeing it down. And keep spraying more on while you continue to squeegee to keep the squeegee from sticking to the film and pulling/stratching the film which causes you to have to rework and entire area. Also its crucial to squeegee from the middle of the window out in all four directions, not top to bottom or left to right, etc. NOTE: you can pull the film back off the window in the middle of application if absolutely needed, but if you do, make sure to spray the window and film back down again to help re-apply. I do not recommend doing this unless you absolutely have to, in order to fix a crease/fold/large bubble because when you pull the film back and press it back down, you may cause more bubbles/folds.Even after doing all of this very carefully, like we did, you will most likely still have quite a few small bubbles/pulls/lifts which are not very visible from the inside during the day, but very visible from the outside. Good luck.

I read the outside of the box when this arrived based on other reviews, and saw it said "internal" ....... was super bummed, but felt like checking it anyway. There's a big sticker on the roll inside that says EXTERIOR.It's rather sticky, soapy water is highly recommended.

This is honestly a great product. Time will tell how it holds up. They send you a squeegee and a knife for installation. Be very liberal with the soapy solution, and watch all videos on their website before trying it yourself. Get a buddy to help and be prepared for your first window to take at least an hour depending on how big, and to not be perfect. Maybe buy a little extra and practice on a window nobody sees very often. The hardest part is peeling the backing off, and using the knife to get the film trimmed to your window.You cant see in during the day at all, and it’s very dark and tinted at night, the mirror effect is opposite during the night. You can’t really see out at night, but you can see in.Oh, and the small bubbles do go away within the next few days after installation. Fyi, YOU CAN SEE EVERYTHING THAT IS UNDER THE FILM ONCE INSTALLED. Even though I cleaned the window well, and used a microfiber cloth, we still have several tiny hairs on each window you can see clear as day.. Maybe use some type of tape or sticky surface after cleaning to be sure the window is totally free of any dust or hairs before installation. Thanks!

easy to install, price is good. privacy is decent (not best). if you buying for heat protection purpose than it is not the right product

Took no time to install

The S15 has the exact same mirror reflectivity rating as the S05 but let’s in much more light amazing quality want to do my entire house and cars lol...
