Difficult to position perfectly for large surfaces, e.g. 2m x 90cm. Wrinkles are created that cannot be corrected. For smaller surfaces, it is easier. It needs quite a lot of water on the glass, and on the nylon on both sides.

if you spray water as it says, it doesn't stick to the glass at all. if you use it dry on a large surface, it creates bubbles.

Fine for 2 years now
Be careful during application: spray a lot of water with a drop of dish soap so it slides and you can adjust the placement
Spray on both the glass and the film. Don't be afraid of spraying; it's for the best and then it will drain off.
Then, with (a lot of) patience, you will remove all the water and bubbles with its squeegee.

Very good product. For installation, you need to have a wallpaper spatula and a water spray bottle. I only had difficulty with the first piece. After that, I found the way. If you consider that outside they ask for 25 euros per square meter!!! then it's worth spending a little time on it. We needed 40 sq.m x 25 = 1000 euros. So I think that even the 2 days I spent on it were just fine.

It is quite covering, just as I wanted. However, during application, we struggled a lot because it easily cracks and traps air. The application is not easy, even with two people.

Value for money. It is very large in size so that if there is a mistake in the installation and air gets trapped, you have the margin to put in a new piece again.

It really wasn't worth it, it is impossible to fit it properly as it traps air inside, and no matter how carefully you try to apply it with a special spatula, the result is disappointing.

This is an affordable and high-quality solution. We used the sticker on the storefront and the result looks very nice. The installation is also easy, although we used dish soap and water for better application.

It was easily installed and appears to be of good quality, it will be re-evaluated over time.
