I have been driving for many years my vehicles with wind deflectors. So far, always with very competitively priced models and without any problems. This time I first shopped times a wind deflector with ABE. Right from the beginning again and again, almost always, problems with the windows. The pressure control lowers the disc again. And even better, at the first ride on the highway, the wind deflector is losing his grip on the driver's side and slips. Could just on the side strip and save the part. After that I did the part attached with double-sided tape. But now it keeps the problem with the windows still exists. Annoying. But without wind deflector is repeatedly rainwater in the car.
