Have gained for my Opel Astra H as a substitute for the original Opel wiper me the Bosch Aerotwin wiper. For the price and the offered wiper performance unbeatable, quiet and an absolutely clean Wischergebnis.Selbst in freezing temperatures, which we already have now, wipe a super-silent. For me, a great product that I can recommend to all, who are looking for a replacement for the original wipers of your car.
