This is now the 5th carto in as many days I've tried with this juice. The same thing every time. Initial fill fine ... one or two refills of 4 or 5 drops per normal (like I would with any clear liquid), and then the cotton mushrooms and after a pull or two goes black on top, not absorbing anything more without it going straight through the air hole. It's done this on both 2.0ohm and 3.0s consistently. This is a white chocolate flavor, it's not nearly as dark as a coffee flavor. Cartos aren't cheap if you start going through 1 a day, so what's the deal?
I've also tried this same stuff on an atty, although I'm fairly sure the Joye atty I got was garbage, as all flavors tasted nasty and burnt from the getgo at any voltage between 3 and 4. Then I tried a CE2 tank, and it worked for 1.6m and then stopped wicking entirely. This is currently the only bottle I have left so this is getting frustrating to say the least.
Further, considering that all the juices I get are 30/70 vg/pg, what difference is it that the darkness makes? Clear liquids such as blackberry work outstanding so I fail to see the cause of the dark menace?
