Do a quick "Power-Suck" with your cheeks BEFORE you hit the button and THEN take a "normal / timely" drag of vapor...In doing this, you're "squishing / compressing" the cart packing, effectively squeezing the still-saturated part of the cart into the dry part near the atty...
in my opinion its not about the cartridge, but about the pooled liquid beneath the atomizer.
try it without cart and only the mouthpiece. drag normal and after that do the powersuck thingy. you will see.
i did this allready with my kissbox, and with older atomizers. no need if they are new.
