I saw these things a few months ago.
Definately interesting, although - and this is my personal opinion - it is too bulky for my tastes. At least it would satisfy the turtle community as it suddenly justifies their helmet usage,
I can't see the video, so I won't comment on it.
I'd be curious to see the airsoft versions. Coming from a real steel manufacturing community I'd also suspect they'll be far exceeding of current airsoft equipment requirements, ala Magpul PTS, so I don't see how they would be any ballistically inferior to a paintball mask (not like you need anything more than a sheet of thick plastic for BB's, anyways).
Good review, interesting and refreshing product.
