I have these wiper blades for some time on my Seat Leon 1P purchased last winter in which the old wiper blades have only made streak and have already badly "geschrappt" by the curing. Even at high speeds on the highway a controlled ride at a constant cleaning action. The series wipers have a slightly different form, making them louder. When A160 from the W168 series I have these wiper blades also mounted and there really are worlds absolute buy recommendation!
