Hey Drott...you don't have to get new attys. The beauty of VV is really the regulated power. You don't rely on the batt & get the freshly charged battery power all the way through. If you like your 2.0 & 1.5 attys, just keep the VV set in the 3.7-4.2v range. You'll get a consistent vape. When you buy more attys, try 2.8-3.5ohm for vaping at 5v.
Cool I do have some 2.8 carto that someone gave me.Ty ag aka ba
