i remember going through 3 packs of smoktech 1.5ohm dc cartos and 2 packs of lr boge cartos trying to get unicorn blood to get a consistent and satisfying vape. never happened, they would all stop wicking well after a few hits, either dry hits or flooded battery while doing dry pulls to negate the dry hits. even though it seems like a thinner juice than others, there's something in the juice that burns more easily than the pg/vg and causes it to gunk up faster than any juice i've ever tried.
