I've bought PIAA products for three vehicles now; their wiper blades for my Dodge Magnum maintained what has been a high opinion of their craftsmanship. A figurative and literal snap to install, their aerodynamic and work very well. PIAA also provides a small container of a silicone-like sealer to enhance the wiper's water repellent properties. I can say this is one of the rare occasions where a manufacturer backs up its claim.-M.D.Las Vegas, NV
