It is reported to be easy to measure, cut, and apply, with one user stating that it took only about 10 minutes to install. The product is particularly praised for the beautiful effects it creates when the sunlight hits it, with rainbows appearing all over. Additionally, it reduces sun heat and glare, making it suitable for use on car windshields as well. However, customers have noted some limitations of the product. Despite providing some level of privacy, it is not completely opaque at night, allowing people to see silhouettes and objects if the window is big. Some customers were disappointed with the lack of color in the design they ordered, as it appeared more like smudged glass from a distance. It is also reported that the product may not adhere well to metal surfaces and is not suitable for use on car windshields. Overall, the B07ysfhk5z privacy film is praised for its ease of installation and its beautiful visual effects when the sunlight hits it. However, customers who are seeking complete privacy may find it lacking, and those looking for vibrant colors may be disappointed.
