Our testing / product development capabilities have contributed to feedback like this:

Five Stars (Amazon):  "I was doubtful but have now become a believer. These things (AirStreamz) work when worn properly. I can hear the car behind me before my radar device can pick up the car. And I more easily hear the beep from the radar device."

(MO - Amazon | Pennsylvania)

Five Stars (Amazon):  "I first tried the Windfree. They dampened 1/2 of the wind noise, but there was a high frequency noise / whistling left over. Then I tried AirStreamz and honestly did not have the highest expectations. All the more astonished I was when I drove off and the wind noise was suddenly completely gone. Okay, 5% may still be there, but the difference is like day and night."
