if you are willing to put up that kind of money i would highly recommend the evic, it may seem complex but it will take you no time at all to figure it all out. i have the provari mini, lavatube, and the zmax all of these will take you more time to figure out i would thing. the evic can charge your
batteries without taking them out of the device! this is huge if your on the go also there are now 18350 tubes that make it much shorter and pocket friendly and the most amazing part is it has upgradeable firmware at first i thought it would not help much at all but the upgrades they have introduced have been a vast improvement! i would recommend either the regular size vivi nova or a dct
tank for these because they both look great on the evic.
