I am 6' even on height, I adjust it to be at the bridge of my nose and it shakes my helmet and face so bad it is like looking through your rearview mirrors at everything! I raise it up to look through it and eliminate that problem, but there is such a gap between it and the headlight that it forces air right up the speedo and into my chest and drives me nuts. I was much more comfortable without a shield, but I do alot of night travelling as I am a bondsman, and the bugs tear me up, so I just spent $350 on it and the brackets and hate it. Any suggestions out there. Thanks.
