Trying these on the Subaru now instead of the rubber covered winter blades. They're really nice, but I've only had them for a few months, and any blade works fine when new. They do maintain great contact with the windshield with no chattering like hinged blades. Great aerodynamics, too, even without the little wing on the OEM blades.
