The Issue which JC is not wheather the product is good or not--rather "Is the product good today". As I have said, I have been ordering from them for 7 months now and every once in a while you get product that either tastes wrong or NOW we have an issue with the product being too thin (like water). So it will not vape let alone hold in your cartridge.
When you buy a Coke, it tastes the same everytime. As a matter of fact we do not even think about whether it will taste the same everytime with a Coke. That is called Quality Control.
Botton line here: We should not have to worry when we order from JC whether we are in fact getting a "good batch" or a bum batch that is for the most part water that runs right out of the cartridge------Sun
