You know I'm not sure what this HA type 3 stuff really gains over type 2. Sure, type 2 gets worn and looks ugly after you've used it for a while, but that's better than looking ugly the day you get it brand new.
Anyway, I don't think those shells should have been sold as firsts, at least not as premium firsts. Not necessarily as seconds with no warranty, but maybe as "firsts with full warranty except for this specific known, no-effect cosmetic blemish", at a small discount. Or the stripe could have been specifically described in the FITD special with the explanation that that's why they're on special. Users don't necessarily require perfection in every detail, but they do want a product that fulfills their expectations, which means don't give them unpleasant surprises.
