These things work. This is my second one. 1st one was used on a custom Triumph Bonneville with a cafe-screen. I drilled and attached it. This one is 'clamped' to the top of my CALSCI windshield for my CanAm RSS Spyder, (2012). It's quiet behind the screen now. Don't get so wet in the rain. Just finished a trip from FLA to Maryland, and back. Had to get a closer look at our deposed Federal Capital. It worked great.
