The product arrived promptly and in perfect condition. My windows look like a silver reflective mirror on the exterior. I am very happy with the level of privacy this film provides however I should clarify a few things about it's effectiveness. The level of effectiveness depends on where the light source is. What I mean by this is, during the day the light source (i.e. the sun) is on the outside and my home is darker on the inside, so passersby cannot see in my home. I can walk around in my pjs and be invisible. But because I have skylights and the back of my home is all windows, when the sun is shining in brightly - and, I have a strong light source inside my home - passersby are able to see movement inside and see my outline (when not standing directly in front of the window). They still cannot see details, like what I'm wearing or if I have rollers in my hair. However, when I'm standing directly in front of the window passersby cannot see me at all, despite any light inside my home during the day. Night time is a different story. It is dark outside and the light source is now inside the home so passersby can see everything! Either keep your lights off or invest in some blinds - you don't want to be one of those neighbours! When it comes to looking from inside-out I can see perfectly clearly during the day, although there is a slight reflection. The caveat is that it makes the interior of my home darker during the day (like a rainly day) as it filters the sunlight. The silver lining is that is prevents uv rays from damaging my furniture and keeps my home cooler than usual, reducing the need for AC. The clarity is also perfect at night when looking out. Because the interior windows have a mirror-like quality to them at night it produces a strong reflection so turning off interior lights is needed to see outside. With respect to installation, initial installation was tricky however with practice became seemless. I would not recommend installing alone, ask a friend or family member to help. Steps followed: 1) Lay film on the table and cut to size; 2)Take over to window; 3) One hold two top corners of film while other peels 50% of the backing off; 4) spray the window & outside of the film with soapy water (avoid plain water as soap makes it easier to smooth out the bubbles and avoid ripping the film. Use dove dish liquid dish soap); 5) person holding the film, place two corners of film in two top corners of window and hold while the other person carries out the next step; 6) starting at the top of the film, place scraper in middle and run it towards the right, pressing firmly to eliminate any bubbles/water under the film (don't worry about tiny bubbles, they will evaporate and disappear over time). Place scraper in middle again and run it towards the left; 7) repeat this as you work your way down the film; **Note** Be sure to continuously spray soapy mixture over film to ensure scraper slides effortlessly and you do not scratch the film. This will also allow you to press harder, eliminating bubbles and ensure smooth application. Overall, I would absolutely recommend this product if your main goal is to achieve privacy during the day, prevent harmfull uv rays from entering your home, or to keep your home cool of those hot summer days. Great product and very happy with the results.

I live in a first-floor condo where privacy is non-existent. People frequently walk on the grass through my yard - very close to my windows. I felt quite uncomfortable having my blinds and curtains open as anyone can see in at any time. I did my research, on Amazon, to determine privacy film products with the highest ratings. I purchased this product in August 2016 and installed it several days after I received the product.It took me roughly 3 hours to do 2 windows, however, I just had foot surgery the week before so my movement was slow. Plus, I wanted to be certain I was following all of the instructions for good installation. Putting the film up was not difficult, following the instructions precisely is critical. Apply the adage, measure twice, cut once. I measured three times - just for safety. I have had the film up on my windows for 2 months now. I love it!! There are multiple benefits: privacy - no one can see in the windows during the day. If anyone tries looking in they only see a reflection of themselves. Night time is a different story. You can see in unless you have an outside light above the windows or you have porch lights on. That helps block viewing in at night but...I close my curtains. Many of my close neighbors have asked what I put on my windows. I rave about the product to anyone who values privacy. Another benefit of the extra dark film - my home stays cooler because the sun is not beating through the windows. Another benefit - I can leave my curtains open so my dog can sit in the window and look out. That's a minor benefit but it's something she likes to do.I highly recommend this product. It's a bit pricey but worth every penny spent. Buy it - you will not be sorry. Just make sure that you have enough film to cover your windows. Measure your windows; pane to pane horizontally and vertically. Allow a little extra selvage for safety. Times it by the number of window panes you want to cover then order accordingly.

Excelente calidad, solo hay que tener cuidado al instalarlo, ya que tiene pegamento y se puede pegar en el mismo, es mejor despegar la pantalla protectora completa y agregar agua jabonosa, tanto en la pantalla como en la ventana.Compare una ventana donde solo le puse a la mitad, contra la que no le puso y redujo la temperatura 2.4°C.

By wthe third window I nailed! Watch the video and follow exactly, the secret is making sure you wet both the window and product well. I back on to a pond with a busy walking path and it’s so nice being able to keep my blinds open and have some privacy now. The product works very well, I’d highly recommend.

i’ve only had it installed for a month or so but it seems to be holding up well. does a good job reflecting heat and light out, the privacy thing is secondary to me, but it does a good job in that respect as well. for all but really small windows, a second set of hands is definitely an asset. nice that it comes with install tools.

Muy buen producto

Pain to install but it works. I have privacy in the day and my home is cooler. Good product.
