man, i was going to get a provari then i see the jbox, now i don't know what to do!!!! i love the custom wood and inlays, pure sex!!! is there a difference in vape power? if i can convey that right, like is vv stronger/powerful compared to vw and vice versa? also how long does a 2200mah panasonic battery last? a year? 2 years? kinda sucks he's gotta tear it apart to replace the battery, too bad it didn't have a locking sliding door on the bottom...
