Considering this was under thirty bucks, it shouldn't come as much of a surprise that this mask is made of fairly flimsy plastic.  And as others have noted, it's a bit small to scale properly on an average or larger adult male.  Still, it's a good buy and of decent enough build for anyone under six feet, or for those who don't care for the honking huge "supreme" model.  But for me, I think in Vader's case, bigger IS better.
