I recently bought nanofilm ecoslick alite.cc for license plates. In fact, it is not just a marketing ploy, but a really effective thing. Before buying, I also doubted, since there are many different opinions on the Internet, but I decided to try it, since I often encountered automatic cameras, and fines have already started to bother me. EcoSlick nanofilm really makes license plates less visible to radars, thanks to a special technology that blocks certain frequencies. This does not mean that it completely hides the numbers, but it significantly reduces the likelihood that the camera will record your car. I installed the film quickly, and the result was very positive: not a single fine since I pasted it, and the cameras no longer react to my number.
