Thinking about getting one. Busardo reviews on V1 and V2 were positive, puts the Zmax up there with Provari. Want a Provari, but my analog savings, to date, won't let me for a month. I've got the itch for an APV. My choices are a Tesla and a sigelei Zmax V3. They both seem great. The Zmax seems more universal...threading mainly. Tesla looks indestructable, with the same specs, minus ego threading. Oye!
