I think the quality of the original Bosch spare parts (Wiper blades here) you need not to speak normally. This delivery took place even Amazon accustomed quickly just before Christmas. Only the self-assembly on the vehicle you have to employ something. The wiper arms are according to the manual of the car (here Golf Variant) to move into position easily when you know how it goes. When dismantling the old leaves and inserting / attaching the new image pointers to help on the packaging, this also a bit tricky but all in all results in a significant savings compared to the workshop prices and takes only a few minutes. The first impressions and results on the windshield are just as good as in the workshop sheets, the only noticeable difference can be seen in the adapters, ARISING in the mounted state not so elegant, smooth cooperation with the wiper arm as the originals. In addition I have set up a photo at the customer images. The function is thus not impaired and the difference is only on closer inspection to. Whether these Bosch also leaves about 40,000 km with wind and weather to survive, such as the built-up of the service centers, the practice will prove.
Supplement the end of March: By now the leaves have completed their service for good 3 months at ice / snow and sometimes sunshine to my satisfaction. Since a few kilometers have come together with me as a commuter. Addendum September 2014: Slow makes the wiping performance, by now well after 30.000km. As a substitute comes back the same product on the glass.
