Yeah. The price isn't low enough to make me quit buying the superior product from my normal vendor. They're only 20 cents less, and so far, not even close in performance.that carto is what came in my tanks...those "holes" are super weird to me...not gonna lie....i am a little afraid of what the filler is (but maybe i should be more curious about what any carto filler is).
i haven't really used them...i think i tried one but it was really low resistance....they are in my "in case of emergency" pile
p.s. the price on those cartos isn't that much less than what i pay for ikenvapes...or any other carto really
