I purchased one of these helmets, good value for the money. However, got home, took off the sticker on the flip-down shield, and found too much optical distortion just off the right of center. Took the helmet back, asked the cashier if all the visors were defective or if I should try to find one on another helmet that was OK. Cashier said they are ALL optically defective!
Too bad, I liked the helmet otherwise.
The older I get, the better I was.
