All I see is a direct replica of a very specific helmet used in filming. This is not supposed to be a generic "put it together yourself to resemble the helmet you want" kinda helmet. I've seen many fiberglass one-piece stormtrooper lids on eBay, but these are all copies of existing "have to put together helmets" and has no ties to an exact, identified screen used helmet, afaik.
For that alone, this helmet is unigue. Not assembled - not as close as assembly could permit to the real helmet - but the EXACT shape and assembly to the real helmet. Of course, some corners were cut and some shaping was apparently required - it doesn't have the extreme details that people apparently want and it has a few minor discrepancies, but nothing to really detract from the overall helmet, imo.
I think it's an extremely nice looking helmet that has a very specific look to it and ties directly to the real helmet.
Though, I'm more of an ABS guy myself, but I can still appreciate this helmet for what it is.
Just my 2 cents.
