I was initially skeptical, but at 5 euros for two replacement blades 70 cm, it was worth a try. And it won! First, it is indeed of Aerotwin wiper blades. It is effective and silent. There is not a trace when scanning sweep the windshield. Regarding the wipers Aerotwin, be aware that they are made clipped elements and therefore fully removable. The only difficulty is to remove the two small caps on the ends of the brush. You have to use a small screwdriver to spread the tips GENTLY. The rest is a breeze. Do not attempt to slide the blades, the old or the new, they are constrained to the center to prevent slipping. Also make sure to put in a good way the small notch on one of the half-blade steel supports (notch facing inwards.) A great buy at a very fast seller.
