Bought a Shoei RF-1200 for $500 and added the $200 transition lens. Works well, happy with it.
I feel quickly could be relative for some. I think its a pretty quick transition to dark, but not back to clear. The only thing is it doesn't get completely black, but still gets dark enough for sun protection. But would be that mirror black you would get from a dark visor.how do you get on with the visor, does it transition quickly?
