Wiper does not the

Ordered the wiper blades, they have the same installed.
Have been looking forward because the wipe look better than the original and reasonable.
But then I had a strong squeaking noise from the driver's wiper.
The thing viewed ...
The wiper on the driver's side is a few centimeters too long, thus he squeezes during the wiping process under the wiper arm.

When I, alas, had to use my car and it even rained as in flow, which was squeaking with a knock combined, the plastic on the outer of the wiper struck each of the wiper arm, causing terrible noise.

I still want to test the wipers, I just sat down, the driver wiper disassembled (left side of the photo) and to exactly 4cm cut.
All together, the car mounted again.

Behold, now no longer squeaks, the wiper no longer has any contact with the wiper blade ...

My Conclusion:

+ Usable wiping results
+ Optics in. See, for original
+ Comparatively cheaper wiper blade set

- Plastic particles can quickly dismantle break in, because the plastic is getting old ... back armor is cumbersome
- Wiper too long, does not fit, must be edited (about 10-20 minutes of work, depending on the tool)
- Seller speaks relatively poor German
