The quality was pretty bad it almost seemed used. I waited two months so I'm just going to ignore them since my car is my daily and not a show car. I also don't think anyone tested this past 70mph (it's probably weird to have windows down 70+ anyways). At 112mph the buffeting happens again and at 90 mph you can feel the wind slapping your shoulder and if you rolled up your window 25% the wind will start slapping your eye haha. Keep in mind when I was testing this it was windy outside. With all that said for the most part it fixes wind buffeting and this is the best looking solution. There is another wind deflector with a larger flap so I'm curious if that prevents buffeting it at higher speeds compared to this one

Best purchase I have made really works great and looks good
