Review on Frameless wiper blade Bosch Aerotwin AR601S 600 mm / 400 mm, 2 pcs. by Micha R-m ᠌

I bought brushes in the winter, after 3 days they creaked. Took it to the store where I bought it, made up from sent a claim to the supplier. The answer came, I quote - “On both brushes, it is clear that the coating has been peeled off from the working edge. Most likely, these brushes have been rubbing frostbitten glass for a long time, trying to clean it from frost or ice. I cannot confirm the warranty case, because such damage is not are a manufacturing defect." How so? These are not my first brushes from Bosch, usually they take care of 1.5 - 2 years. And here in 3 days, in winter, I wiped frostbitten glass, of course, and what kind of glass in winter is minus 10, frostbite. Didn't go for examination. Conclusion, the quality is not the same! I do not recommend buying, the price is 1900, January 2022.
