I have this product on my daily, my wife's daily, and my track car (that no longer has windshield wipers). It's even better than Rain-X plus it lasts years without having to reapply once every couple of weeks. I almost never use my wipers anymore. On track, I did an entire session in the rain at Road Atlanta and never felt like I needed to pit due to lack of visibility. It's really hard to argue against paying such a small price to add so much safety and convenience for several years.
Using this product for the first time, and so far really pleased with it,
Already seen a few days of rain on my hybrid and unlike other brands, the precision sight shows no signs of giving out
Awesome product I like it very much
