A greater concern is that the vendor doesn't seem predisposed to look further into the apparent consumer/client concern, seeming content that its being created in a lab is sufficient evidence that it is of high quality. Further, I would want to see some sort of quantifiable evidence that it is not 'harmful' (any more than any other e liquid may be) as a potential consumer. "Third party...lab" doesn't give me much comfort, when the third party could be XYZ fly-by-night manufacturer with a small pop-up trailer in a third world country. (just sayin'...I'm sure it's not, but it COULD be.)
I agree....
