I think the RPF discussed and continues to discuss this helmet at great length (like over 5 pages).
Overall people seem to like it but there are a few who believe that the 'movie-accurate' claim isn't wholy accurate.
Different approaches to nailing down size and proportion and so forth.
The helmet looks nice to me, I like the look, and without knowing anything about quality of materials, I think it's a great helmet.
Just my thoughts,
Phil
