Niviy Static Cling Non-Adhesive Window Film Frosted Glass Film Bathroom Door Glass Decoration Window Film Privacy Covering (41.2"x 314.9")

So much easier than I expected. I applied it on 3 windows hoping to block the sun and keep the house cool during summer. I can't speak to its effectiveness there yet, but if you are worried this is going to be a difficult chore- it was not.It took me about 30 minutes per window, including cleaning, cutting, and applying the film.. and I did it alone.A few notes- I used masking tape to help remove the backing film, a misting sprayer, a shower squeegee, and water with the tiniest bit of dish soap- worked GREAT! I could slide the film around when the pieces were @ 24 inches long, anything longer seemed to have too much adhesion. One warning- it's full of static electricity so it attracted some cat hair. It didn't seem to affect adhesion, but I suppose it could if it gathers enough fuzz.I chose to buy two sizes and piece them together on the window because the price of the smaller rolls was excellent. I could have lined the seams up better if I wanted to spend more time, but I'm fine with the appearance... it sort of looks like velvet.I'll update later when I have an idea of how much heat it deflects.Update: I've had this on windows for a couple of days. for reference- I live in Michigan and have two windows that get full sun for 3-4 hours in the afternoon. Prior to adding the window film, my house was regularly heating up to 77+ degrees by late afternoon. I do not have central air, so I am looking for a solution to keep the home cool. I put the film on the larger of the two windows. Each day since, it has been sunny with outdoor temperatures in the 60's. The inside temperature has been no higher than 74 degrees. That's at least 3 degrees less and much more comfortable than before I added the film. I expect this will help my portable air conditioner run more efficiently, and possible less often.I'm really happy with the purchase.I also use the white film for privacy, but it does not have the same sun blocking effect, just an FYI.

Ok, this is an honest review based on hours of research in choosing the right film to give privacy in our bathroom without blocking too much light. The ones that look like stained glass are very pretty if that's the look you want? However they are not actually colored it's a prismatic effect from the sunlight shining on it. I'm not looking for that I want privacy not glistening rainbows. Then there's the pattern ones with birds and the like. Some of these offer privacy and some don't, choose carefully. As this is my bathroom/guest also, I'm not looking to make the window a focal point of design. So I ordered privacy film with a slight floral pattern (trying to please wife also). That being said my careful research paid off. It met my expectations.Now for the second part of my review the installation. Lots of things to address here. First I will address the naysayers who's film didn't stick. Your wrong you installed it incorrectly. How do I know, well I'm a semi retired professional wallcovering installer and own my own wallpaper installation company. I'm a licensed contractor with over 40 years experience of hanging wallpaper every day and trust me when I say the process is similar. First of all examine your product keep it in a warm room for at least a day not your unheated garage in winter. Examine the product and determine which direction you wish to install, vertical (easier) or horizontally. Cut the film about half to 1 inch bigger on all sides. Don't cut to fit beforehand. The product has a film on the back that MUST BE REMOVED or it will fall off and you will be using scotch tape and complaining here. The smooth side not the textured side is the side that will stick to your glass which will be on the inside of your home, not to be installed on the exterior side of glass. So now you have your pieces cut correctly and are ready. But first you must thoroughly clean your glass and remove all contaminants especially flecks of paint, dust, dirt etc even invisible microscopic grain of dust will cause bubbles, similar to that protective film you badly applied to your phone so paid the guy at the mall $20 to do correctly. I recommend using isopropyl alcohol or other cleaners such as paint thinner or even acetone (nail polish). After that use vinegar and water or at least Windex. Get a nice pump fine mist spray bottle add water and a drop of detergent shake and spray the glass thoroughly and evenly. Keep a towel handy to wipe up drips and all the goo from the window sills you never clean. Apply film and slide into position butting one long side to the edge of glass or trim.gently use a squeegee preferably one with a no scratch felt side to push bubbles to edge and out. You can buy these on Amazon or big box stores or use a flexible wallpaper plastic or heck even a credit card will work. Once you've got 90% of the bubbles out except at edges use your plastic FIRMLY TO crease the edges. Take your snap of blade knife and run the knife and plastic along the edge, lift up the corner you can't cut and cut with the knife or scissors (better) that last 1 inch. Rinse and repeat. You will have a few small bubbles. Check your cuts where the bubbles are and it's probably trimmed too fat and putting pressure on the film which causes it to bubble, re-trim using the knife on the inside of the plastic this time. You may get 1 or 2 small bubbles. Don't worry wait a couple of days and it will shrink and suck in to the glass adhering tightly. You can also make a tiny, tiny cut into a bubble with your blade and smooth down if you like, but please don't poke with a pin or you will have a permanent visible hole. After several days you will think that a professional like myself installed it for you and you can pat yourself on the back as you have saved yourself hundreds of dollars on installation and can volunteer to do all your friends and neighbours windows. Your welcome, good luck !!!I'm Gary and I install "Ultimate Wallcovering" in Southern California, and I approve of and recommend this product. Remember....measure 3 times cut once !!!

It took about an hour to apply the film to two windows and did require two persons to do so. The results were even better than expected ! The film gives a subtle sense of a lace curtain and is beautiful .

Good, heavy film; I bought the black color and it definitely makes a difference in heat coming in through the windows. I also have roller shades, but I prefer the window film because it still lets me see the backyard and keeps the room cool.I put the window film up myself, and I found it somewhat difficult to cut the excess film with the utility knife; in the end it was not even

I bought this item to cut the heat from the west sun. I read all of the instructions and tried to carefully follow them. The product is thin and does want to stick to anything. In the end I did not manage to install it smoothly. Perhaps my inexperience. If you want it done perfectly, use a lot of water and perhaps have a second pair of hands. However, my goal was accomplished because it cuts the heat beautifully. And for that reason, I'm satisfied.

Shipping was fast and arrived earlier than expected. Very easy to install. I did follow directions and the use of lots of water made it so much easier. Would buy again.

Good product as mentioned and easy to install. Highly recommended

I am using this product as a background for a craft project, which I am going to be putting out on my garden. I could paint the glass background, but I wanted to try the cling privacy. It turned out pretty well actually.
