I put this shield on my old helmet the other day and wore it for the first time today and was really surprised at how clear it was. It was so clear I actully doubled checked to see if it was all the way down and I was not looking under it. What a pleasent surprise.
Fit well on my helmet. Anti-fog worked great. Not too sure about the ratcheting mechanism, seems a little cheap. Don't know how many cycles of opening and closing it will tolerate before wearing out. Only time will tell!
