I'm happy to take 'made in china' at face value. They didn't seem to see any need to clarify beyond that so I'm not sure what there is to argue about.
I just feel that trying to paint the picture that this is all being made south of market by a workforce obeying all pertinent California/US health and safety regulations is a bit disingenuous when it says "Made in China" right on the unit.
I'm still using mine, I'm still very happy with it, but it's best not to be under any illusions.
It is, technically, "made in China", which is why that's what it says. And it's great that there are users for whom this is sufficient. However, there are many users (me being one of them) who are even happier knowing that a couple of the most important elements are made in the US...for me this is less about safety and more about efficacy (knowing the heating element is made here is huge for me personally, just because it's such a critical and potentially finicky part of the device).
No one is saying the assembly meets or exceeds all US safety standards, nor, do I think, that's implied by talking about FF supervision. But it's also important to separate the kind of Chinese manufacturing that many people picture in their heads (there was a post a little while ago implying that Chinese workers aren't really paying attention to what they are doing from one unit to the next) and a process that is overseen by FF themselves. I have no idea what that looks like, nor do I have the knowledge to assess it even if it were unfolding in front of me...I do know key FF folks are constantly in China, working with the manufacturer there.
There isn't anything to argue about, but I personally think it's useful for users to know more about this process, rather than just "made in China", which has a whole slew of implications for many folks. (Just peruse any of the threads here to get an idea of how many people react to "made in China" when it comes to their vapes.)
