Great price, easy install; fit My Volkswagen Tiguan 2023 S. Glad I waited for next day delivery instead of going to autozone where comparable wipers cost $45 and that was WITH two coupons!! It would have been $60 without. The ONLY thing that could be better is warning you to make sure when you’re pressing in the wiper that you hold it from the very top or else your finger will slam down into the trap part and it will hurt like heck and make you bleed (personal experience this afternoon…) Otherwise great. Took off one star for that but maybe Im the only person thats ever happened to? (Im doubtful.) its not directly related to the product itself but just would be a helpful tip for ANY windshield wipers to include!
