The Lost Mary 4in1 offers more puffs per pod change than standard prefilled pod kits because it can hold four 2ml pods at once. How many puffs four pods will offer depends on which user mode you choose.
The normal mode offers up to 2,400 puffs from four pods, while the ECO mode can offer up to 3,200 puffs from four pods. This is an estimate provided by the manufacturer, but the actual puff count may vary depending on a number of factors.
