Very poor quality. Difficult to install. Not at all durable as a material. Zero resistance to the passage of time. After two years, the film is as if it doesn't have a membrane (the only area that still appears "dark" is under the rear windshield wiper, as shown in the photos). It would have been better if I had kept the money and went to a professional.

The placement is a joke. The membrane does not come off the paper at all. It is an incredibly thin thing in dark gray, not black. Money wasted!

-Very good quality in relation to price.
-Very reliable protection. It is indeed 15%.
-Quite dark and compared to other options, it has a slight brownish tint from the inside, but it doesn't look bad.
-First time installing tint on a car. It took me 2 hours for each window to be done properly without bubbles/empty spaces.

The review concerns a darkness grade of 15%. It is of higher quality than cheap anonymous products with a brown color, not black, slightly glossy, which may appear reflective to some when looking through the car. Its installation is difficult due to the satisfactory adhesive it has, but if it is installed, it will definitely be rewarded as it holds shade and gives a nice visual result. For this price, I consider it decent. However, there should also be a sticker in the packaging that is placed on the glass with information such as darkness grade, film thickness, company, etc.
