I want to start by saying the front wipers are amazing, I love them. They fit perfect and work well. However, my one star rating is for the back windshield wiper. I turned the wiper on to clean and it became jammed in the top part of my door hatch with a dime size width gouge on my car and was about 3 inches in length when all was said and done. I don't hardly leave bad reviews...buyer beware on this one.
