...about three weeks ago. Ironically enough, it was my wife who ordered it, and not me. My wife, bless her heart, is the kind of gal who gets bored with things quickly, then moves on to something else. So she gave me all of her vaping supplies (she was never a smoker to begin with, but just wanted to dally around with a tank, several blank carts, and 0mg e-juice).
Well, being a person who hates seeing things go to waste, I picked the tank up one day, studied it, googled videos on how to use/fill them, then ordered some 18mg e-juice. I had been using pre-filled carts up to that point, and long story short, I quickly discovered how much more economical and satisfying it was to use tanks. These things are a God-send, and I hope Vapor4Life never stops selling them
Tanks are definitely the way to go.
