The quality of the windshield is very good. The design and function is very good, however the one size fits all is not so good. I had to pay extra for 1 inch handlebar clamps because it came with only 7/8 inch clamps. The bottom edge of the windshield sits about 6 inches above my headlight which allows a lot of wind through.
In spite of the negatives it still seems to be the best option for the money. It has stopped most of the wind and is quieter than the last windshield that I had. Knowing what I know now I would still recommend this product.
