You have to be careful and know your sources when doing any kind of DIY e-juice. It wasn't to long ago that there was a serious scare in the in the community about mislabeled nic base. So we want the best base @ the best price. Right? Right..
So what makes them the best in my humble opinion?
Price
Base Clarity
Customer Support
Nic Level accuracy
Packaging
I have found no flaw in this vendor yet. They excel in all categories.
The best part about it is, they are the lowest priced nic vendor I can find.
They also have an outstanding selection of flavor concentrate served up in 8ml glass vials ($1.49). They also never fail to throw in a freebee or two.
