Sorry Bonnie, Foggy just informed me you picked up a Z at vaporrange ( great shop) its an excellent and safe regulated mod , you'll need a tank like a nautilus/ nautilus mini that's not sub ohm .....sub ohm tanks/ heads will not work on the Z , but that's not a problem, just pick up a nautilus at 1.5 ohm s ( I'm not sure of the choices in ohms ) and you'll be good to go.
