Another feature that stands out is the asymmetrical wind spoiler. This design uses airflow to increase the blade-to-windshield contact, ensuring consistent performance even at highway speeds. For someone like me who often drives long distances, this is a significant advantage. Additionally, the wind spoiler shields the tension springs from harsh weather, contributing to the durability and long life of the blades. It’s reassuring to know that I won’t have to replace my wipers frequently, saving me time and money in the long run.
