The comfort is really good. After a few seconds you do not notice really, that you are wearing a helmet.
The optics I find really ok. This is of course a matter of taste but if you like it more subtly, is hereby will certainly happy.
It is, incidentally, still a sun visor in which you can clip it on demand to the helmet. The Schutznupsis who are there in the mounting holes are, but really difficult to remove. Since one should possibly overturn with NEM tool and not with your fingernails. (* Ouch *)
