information about anti-radar stickers

Hi! I recently came across information about anti-radar stickers for cars and was a little puzzled: how effective are they in practice? Have any of you already tried them and can share your experience? I am interested in whether they really help reduce the likelihood of radars being triggered, or if this is more of a marketing ploy. I would also like to know about any nuances of use - which parts of the car are best to stick them on, are there any restrictions on the type of coating, and do these stickers affect the operation of other electronic systems in the car.

I personally decided to try anti-radar stickers https://antiradarsticker.com/ after searching for information about the real effectiveness of such solutions for a long time. I will immediately note that I was skeptical - it seemed that this was more of a marketing ploy, but the real experience turned out to be completely different. After installing the stickers, I noticed that the probability of radars being triggered really decreased, especially on highways with speed cameras. The main thing is to place the stickers correctly: I followed the manufacturer's recommendations and installed them on the front and rear of the car, avoiding areas with active electronic sensors, and no failures in the car's systems were observed. I would like to emphasize separately that high-quality stickers do not damage the paintwork and are easy to remove if necessary. For me, this has become a convenient and practical solution that really works and does not require complex installation.
