Nothing beats my kgo and a 3.5 ml tank of
juice, but we have a few volts in the house. My husband uses them at work. He goes to work everyday with his kit consisting of 3 volt batteriess and 3 cartos. We make our own
juice but the hubby sticks to the tobacco flavors. He says a cig should taste like a cig not a lolly pop. My husband is having a little problem distancing from "cigs" and still calls
vaping "smoking" After you are set with the volt kit with the chargers, the extra batteries are reasonably priced. The prefilled cartos I think are expensive.
