Do any of you use one of the "Solid State Covers" face shield?

Here is a link: http://www.solidstatecovers.com/

And a photo of one of their models:



I have several helmets, some have snaps for a shield, some don't. (The German one in particular does not)

This looks like a great thing for the snapless helmets for the rain.

If you have one of these, how well do they fit and feel on your face and head?

Do they block the rain pretty well?

How is the airflow as far as not fogging up your glasses when it is raining?

Overall impression as far as usefulness?

Thank You!

 

You asked for honesty:
Overall impression...

Not in a million years.
Laughable.

But to each, his own.

 

This is the first time I've seen them. They look like they'd limit my vision too much, looking out from a slit. I prefer my tinted one.
