I didn't want to dedicate a new tread for the Isotta screen as it has been discussed already here.
My first impression after riding only a few miles - noisy but a very good protection. My head doesn't bounce all over the place anymore but the stream of air hits me right in the helmet. I am 5'11" and if I lift my head a bit it's quieter and the air goes around my neck, today was also a windy day so I will do more riding tomorrow and evaluate the screen further. The finish of the screen is superb and it looks great on the bike.
