Has anyone tried these Bosch wipers? I got a set in July. Probably done 1.5k maybe 2k since. They're knackered. Streaking badly, missing bits of the screen. Utter mess. Noisy on direction change. This has been there from the begining too. Soo weak too, touch them and they fall over. I've tried clay baring the screen, no difference, Meths, No difference. even fairy liquid incase there was oil on the screen, no difference. Cleaned the blades. Still no good. So I said sod it and bought a set of genuine audi ones. 100000000% better. Do you think it's been too long to take the Bosch ones back to halfords. At £30 it hurts for them to last so little time.
