tried one, hated it... happy with my shoei 1000 and sunglasses or shoei and safety glasses, allows for multiple levels of tint... Tinted shoei sheild plus sunglasses for brightest mornings and evenings riding into the sun, one clear and other tinted for regular sunlight, both clear for night, and my tank bag holds it all, I gotta stop for gas from time to time anyway, so it's no biggie to swap glasses/sheilds. And screw RX glasses, all contacts 100% of the time until I get lasered. also i carry multiple pairs of safety glasses at night, glasses get too loaded with gnats, pull over, swap, ride, pull over, swap, ride...(not something easily done with flip down visor.)
