The reduction of wind noise while moving is dramatic up to about 10MPH. The install looks quite nice.But beyond 10MPH the noise is still too great. The "nooks and crannies" on the face of the camera are the root cause.
To make the camera REALLY quiet there is one further addition required, which is a bit less sleak. This shields the harsh case edges and I have recorded voice through the camera mic up to 40MPH. I did not try it any faster. I tested this holding the camera out the window of my truck, which itself adds wind noise. For biking this mod is totally adequate. For motorcycling I am not sure as I cannot test that.
