How many carto's a day?

[Black Strat]

I have 4 cartos with different flavors and vape them all day, refill them each evening when I am home. I have another two for work commute and one for work. I probably use about 30-50% of each one per day. Keep them topped off and they last weeks. (Yes, I have a ton of batteries LOL)
So bottom line, about 2.5 - 4 cartos per day depending on vaping opportunity.

10....considering a standard sized carto doesn't hold quite 1ml. If they are pre-filled, it's more like 3/4mls. I vape 7-10mls a day of 18mg at 6V.
