When you buy a ProVari, you are buying a tube. You still need to buy
batteries, a charger, something to put on top of it and
juice. You will also need back-up, which is more than just extra
batteries. You bought a ProVari - great, you now own
one mod! God forbid you drop it or lose it, what will you vape in that situation? ProVape hospital is a fast, but not that fast.
