My old wipers were very worn (rubbing the disc, Schlieren) - just very uncomfortable. After extensive research, I came across the Bosch Aero Twins. First, you were very low compared to the local retailer. The Assembly was in a car totally unproblematic (2min assembly, Opel Astra H). In use, I was thrilled: Clean and free of streaks and especially quiet. I can not recommend anyone to save the wiper. Give prefer 10 EUR more, but her trip carefree and safe in traffic.
