These are fantastic and fit my car perfectly. I was a little worried but they went on easily and were the perfect replacement. They fit against the glass and don't cause any smearing. I was thrilled to get them so quickly because we had another storm coming and these worked fantastically. I can see out of my windshield. If you're on the fence about these, go ahead and order, they work great.

Great replacement wiper blades.

These were great wiper replacement for my car, very easy to install and way cheaper that buying them at a auto parts store.
