I've have a flyscreen I picked up from Marty for a couple of years now. I use it mid summer months when it is warmer and the bugs and road debris have diminished. Typically wear a full face with because of the debris. It does help a bit but comes no where near what a full screen covers. With my Roadster screen, I wear a half helmet with little fear of getting hit by rocks. I've been pelted on my full face with the flyscreen many times.
