I don't know, maybe the juice is just a coil clogger, or I'm still doing something wrong. The jiuce is Halo's Tribeca. It's not all that dark or all that thick and I go through roughly 30ml a week. In my experience, the juice tastes awful if I push the carto past 3 tank fills. Oh well, to me it's not the end of the world. But, I'd be ecstatic to get a week or more on a single carto.
Ive had Tribeca and Its not a dark thick juice what kind of carts are you uesing? what resistance? What Voltage are you running them at Are they prepunched or are you punching them your self?
