I couldn't hear any significant wind noise up until over 70mph. There was some light rain and it kept everything inside nice and dry. I did hear a weird whistling sound going 80mph downhill. It only lasted for a few seconds. I must have hit a crosswind.
With this on and driving an average of 70-75mph, I got 17mpg

I bought it from Amazon for $460 - $100MIR and free shipping.
