can you tell us specifically how they are junk (burnt? clogged? leaky? weak?) (back to this thread cause it seems to still have life in it--but shouldn't we migrate somewhere where the thread titles would be more useful)
i bought 4 (all volcanocig.com) no doas but the first started leaking heavily after 1.5 days of bliss. nursed it along until the new ones came in (wasting a lot of
juice, blowing out the atomizer, using thicker juice toking more softly) I've been using the other three in rotation or simultaneously with fresh tanks and each on its own battery. 1 of the new ones is leaking. I've been trying to swap the tanks around and see if its the juice, the tank connection the leaky wick or what. I'm getting dizzy trying to figure it out--and from pulling continuously on 3 great monster vapor machines.
that's the rub. This thing--when it works--outperforms standard 510, 306, 510 cartomizers, and kr808 cartomizers. it is close but not quite as good as dripping on a fresh brand name janty 510 atomizer. it is lso better than the experience i've had when i've bought a box of 5 atomizers from a solid vendor (who i like too much to dis.) and had each in turn fizzle, clog, get burnt, develop weird taste, start producing low-vapor tasteless fog, and only get worse despite an infinitely varying regimen of cleaning with boiling water, vodka, dry burns, wet burns, neutral juice super strong cinnamon juice (to hide bad tastes) etc.
the tank is by no means perfect--i'd say its a half notch above the previous efforts. but it is definitely a step in the right direction.
