Aspire has taken its new version of the classic Nautilus mouth-to-lung tank, the Nautilus X, and, through a feat of engineering that is both clever and bizarre, transformed it into the Swiss Army Knife of atomizers: a 4-in-1 “Survival” Kit, called the Quad-Flex, that can be used to assemble a 22mm 1.8Ω Nautilus X MTL flavor tank, a cloud-chasing sub-ohm RDA (as either a standard dripper or squonker, with either top or bottom airflow), and a Genny-style sub-ohm RDTA tank.
