I bought the Baggershield and can say that it is wonderful for me. I just took it for a serious spin. First with the 9" smoke portion in place. (Today was 80 degrees here in So.Cal. Perfect riding wx.)
Had some buffeting of the helmet at 80 mph and similar wind noise to having the stock shield in place. After chow up in Banning (near the desert of California) I put the additional shield in place--the clear portion, effectively just turning it upwards from its locked place behind the smoke portion. It was a lot like the feeling I had back when I rode with the stock HD Softail Classic shield. Very enclosing and secure-feeling.
Oh my, over-the-moon difference! I rode at 60 mph without my face shield down and could hear the music coming out of the radio! Toodled along a new-for-me road that took me through some awesome places, and all at 50-65 mph with NO WIND NOISE. None. Not a bit. Nada. Nyet. I'm riding with a 3/4 helmet right now, and it was so dinged quiet that I had to stand up on the pegs to feel if it was something crazy, or just how effective the shield was. It was the wind shield, definitely.
Then, just to be sure, I headed back out to the freeway and smoked it up to 85 before I even knew it. Oops... Still, NO wind noise. I did put the face shield down because I could feel some wind drag on it. Still heard the tunes.
My dog, who went along for the trip, approves of the new bike. He has his own "dog luggage" carrier that was in the passenger seat.
I'm definitely glad I purchased the variable-height Baggershield.
