My old wiper blades with wire clips I had six (!) Years off. This set zeicht after a few weeks already the first signs of wear. If the car in the pouring rain is making the wiper with me (Seat Leon 1M) annoying "beat noise" at the end points. Only in journey are the sounds then away because the pressure is present. Overall, things are pretty "labbelig". I really do not see any advantage over the old version with the metal arms. If as far as I'll probably buy the normal again.
