Hi all, the car is nearly a month old and the wipers are noisy, they seem to work ok but they make that dragging sound 75% of the time as its coming down at the bottom. I washed the car and put rainx on all the windows including the windscreen hoping that would solve the problem, no such luck. Are they just a cheap crappy blade? Any suggestions? Best wipers / blades to use? I found these on eBay "Aero Flat Wiper blades"
