One is made in a sterile controlled laboratory environment by a certifed company using certified materials.
The other is made in someone's kitchen, or basement, or spare bedroom, or garage.
Which U.S. importer(s) sells ejuices manufactured in the specific lab in the youtube video? Does that lab use USP grade PG/VG?
I'm less concerned with a speck of dust or a hair in my ejuice than I am with the quality of the main ingredients.
I'm sure some top quality juices come out of China, along with some that are questionable or downright dangerous ones. Which is which, and where can I order the safe ones? What are their brand names? Where are they importing their USP grade PG and VG from (assuming they even use USP grade)?
I can purchase USP grade VG at WalMart 0.5 miles from my house. Where do the Chinese get theirs? If it's so accessible to them, then why send DEG in lieu of VG to manufacturers in Panama, killing consumers?
Johnson Creek manufactures their products in a similar environment, and if a distributor is selling JC, you know where it came from. If someone is buying a product with virtually no label information, even if one Chinese manufacturer is producing a top quality product, who is selling that product, and who is selling a tainted knock off?
You can't assume because of a youtube video and one Chinese manufacturer producing in a sterile lab, that all chinese juice is safe. What about juices being made in a Chinese basement, kitchen, or garage... out of PV and VG of unknown origin... in a country where USP grade is not the norm, and that has a reputation for exporting tainted products and causing deaths worldwide?
