I usually love Rain-x products. I bought 4 Rain-x weatherbeater wiper blades from Amazon.com on Jan 10th. 3 at 22" and 1 at 19". They were a good deal compared to the local autopart stores and the superstore in my area. ALL FOUR WIPERS WERE HORRIBLE. Right out of the package. I couldn't say they wiped.... more of a smear, with streaks from one tip to the other. These are the worst wipers I have ever had. I don't know if it was just a bad lot they produced or if it's typical of rain-x wipers. It's a good thing I use the rain-x windshield treatment. I don't have to use my wipers as often. LOL. I contacted rain-x, to their credit they are sending me a refund in 2-4 weeks. Sorry Rain-x. Going back to Bosch wiper blades. It's a safety thing.RobSLC Utah.
