I have had this product before and had no problems. I recently purchased two to replace my previous ones. One package came open on the end, and slightly sticking out of the package. I inspected the product and it appeared to be ok, so I installed it. After the first use, the blades were not cleaning the window fully, leaving an inch stripe along the top of the blade. I attempted to clean the blade and it actually got worse. Now I have a larger streak, about 3 inches. Upon inspecting the blade, the rubber doesn't appear to be straight any longer.  I was able to tolerate the 1" streak, but can't the 3". Unfortunately, since  I was tolerating it,  I neglected to return these in a timely fashion and now am stuck with junk. I will be replacing the drivers side with a Bosch.
