I've been using Bosche Microedge Excels since reading a recommendation in 2001 on CEG, and loved them for years - on my Contour, my old PGT, and my parents' and sister's cars. Recently I switched to RainX based on what I thought was decent ratings ... I am highly disappointed. They do a good job cleaning, but smear some haze a bit (RainX chemical?) that leaves marks, and are extremely noisy. I had forgotten what it was like to travel on the school bus in rainstorms, but these wipers bring back those memories by squeaking just like the buses' wipers did. Next time, I will be switching back to the Bosche.
