The wiper fits perfectly on the device my Grand Scenic III (BJ 2009), but that was about it. The curvature of the rear window, he comes not cope, so that is not wiped at the top. It will only be used about 20cm from a total of 30.
This seems simply to be a design flaw and is a great pity, because so far I was convinced by Bosch. (Warning: very expensive 0900 hotline to the Bosch side!)
This thing ends up in the trash can and I go to the Renault dealer.
