I 've tried them and so long as the
juice is a higher pg mix (or just thinner) then the horizontal carto works great. My all day vape
juice is BWB malty toffee which is a 70/30 vg/pg mix and I fill my grand with that one. My mini has casablanca which is a 70/30 pg/vg mix. But I find the horizontal ones don't want to work so great with the thicker juice so I just use good old boges on that one and use the kangers on the mini. The kangers give off nice clouds of vapor but they do have a very different draw on them than boges. Some say its a tighter draw. I find they don't seem to crackle and spit as much as the boges do.
