I would put FWP in the category of caution required on the functional end of things, regardless of business ethics. I've not seen anything that suggests their inks are misrepresented, but the from trying several that were passed on by a friend, they are truly a menace to fill from, even when full.
Their center of gravity is way too high when filling, the opening too narrow, and even on the shelf which seems to be where they are designed to look best, the cap is extra heavy and they tip over at the slightest provocation. When I do use the ones I have, it's blunt-nosed syringe only for filling.
