David, I have the Koger and have some mixed feelings about it.
Unless the sun is high in the sky, it doesn't help a lot to shield your eyes from it.
It helps quite a lot to keep the cockpit cool in the summer, when by the way, the sun is high in the sky. In the winter, at my latitude, I need all the help with heat that I can get, so the shade remains folded.
While the unit is well made and looks really good for what it is, I don't particularly like the looks of the think hanging on the top of a beautiful crystal clear canopy, which looks awesome all by itself. Kind of like trash lying in a park.
Like others here, I use an in ear headset with my Tilley wide brimmed hat and that works pretty well.
All in all, I often think about removing it. Right about then, it will come in handy, and I don't......
