I had the original set of blades on my '98 Audi A4 B5, and they used to rattle and squeak and carry on, even changing the blades out didn't fix the problem. Fitted a set of these and now I can't hear any noise, even on a dry window! No thunk when they reach their end position, nothing. Really fantastic, as noisy windscreen wipers drive me up the wall. Best money I've ever spent, will buy again.
