I find I have little use for 1.8mL cartos. The coil/tube/cup, (dub the "works"), are good for larger tank coils. Other than this, They're just a container for my coils to be delivered in. The 3.5mL carto will last me a workday. I'm tiring of messing with them. Other than dry burning the crud to ash a few times. . .when they accumulate so much sludge it won't burn off easily. . .I toss them. Some are frugal to the point of being ridiculous. They're truly disposable. And I'll do what I have to to get them at closer to $5.00. . .even if I have to go abroad. JMHO
