That isn't a mech mod, it's a variable voltage/variable wattage (regulated) mod. A mech mod has no wires, no circuitry, no protection or volt meter/ohm meter.
Mech mods are kind of dumb in that whatever you slap on them, they'll try to fire. Won't read ohms, won't figure out if batteries are over-drained. Using a carto tank on a regulated mod makes a lot more sense to me.
Yup, even if Hell (FDA} freezes over.
When I started out (2011) the FDA was involved in a lawsuit, Customs was seizing shipments, and the end of vaping was looming over our heads.
So I began to looks for ways to become "self reliant", and that led me to mechanicals, RDAs, and DIY. And, a carto tank works just fine on a mechanical.
