I'm thinking about getting one of these, save swapping visor/pinlock over depending on weather! Has anyone used one?
I use one and it works fine, doesn't get too dark though so depends how sensitive your eyes are. Good for me but I have drop down internal sun visor too if required. HTH.
As per their markings, they are obviously not for road use As Frost1 says, they work but are not dark enough for bright low level sunlight in a clear visor. eg sunset. For a compromise, I have one fitted to a light smoke visor to use when I am confident that it will stay sunny / I will be done before dark.
I've just been reading about Sunax inserts. Seriously thinking that a light or medium Sunax with a clear visor and reactive pinlock could do the business 99% of the time.....
