We love them easy to apply with a little technique.
Start at top and stick 8 inches to a foot to window. While pulling remainder of film away from glass, use squeegee to
press film down while moving from top to bottom. This will get it applied very smoothly as there are NO wrinkles or bubbles.
This allowed us to get it nearly perfect the first time. Then just peel back the top part and reverse the process!

I ordered this window film to replace old film for more privacy. It worked great. Followed directions with package and was very please with results. Biggest plus for me was the size film was available in. I covered sliding glass door and adjacent windows 72 inches long. I only cut minimal film. Would order again. Cost was way less than that I bought from elsewhere.

Works really well, very impressed. Easy to remove and reapply if you get bubbles. Looks great when it is up and the light shines through. We had some windows with curved arches and the arch part was not covered by the blinds which created a privacy issue. The film stops anyone seeing in, whilst still letting light in and looking attractive.

The pattern on it is quite complex and pretty and even if you don't apply it that well, from a distance is still looks great.

The window film itself is beautiful and works very well. The service was fine, it was shipped fairly quickly.
The only problems that each roll of window film has a sticker on it that secures the roll and tells you to remove the backing before installing. This sticker is virtually impossible to remove cleanly. It tears and separated and must be scraped off while trying not to crease the roll. Then it leaves behind this ridiculous sticky residue that is also very difficult to remove. There is no reason why they could not use a sticker that is simple and easy to remove.
One other thing, the easiest way to install this film is to start at the top of the window and just let the roll go do down. You remove the backing as you work your way down. That's all great until you realize they rolled the film up the wrong way so that the pattern is now upside down. So now you have to cut off a piece the correct size so you can invert it to apply to the window.
So, two annoyances but still a beautiful result.

This is a great film. The colors it shows are beautiful and overall look is very nice. It makes a plain window look very good and reminds one of the more expensive etched glass windows. The best part, you can always remove it easily and put something else to change it up.
Application is easy and with any film, cut just enough to overlap the glass and a bit more, trim as needed. A spray bottle with few drops of dawn dish detergent is enough and make sure to have sharp razor or utility knife. Best to use the (xacto - I think) knife you can break off the dull portions of the blade.
