Installation works well and can be realized for everyone. I have ordered the wiper for my Golf 4 and also installed at this. The wiper of the passenger side had good 3 cm can be shorter, which I have to adjust the wiper arm again, because the wiper would otherwise drag on the lower window frame.
The wiping result is really good. However, the wipers are very sensitive to small dirt (small flowers remains rich already made to the wiping result to significantly affect)
