Ok I pulled out two of the samples Bad sent me (BTW, I feel I don't say this enough, THANK YOU for everything Bad). I used one to sample some new flavor (LorAnns Naturals Pomegranate) and one with my tried and true Black Cherry. The tried and true is going strong. I didn't rinse or dry burn prior to use, just filled and went. My black cherry mix is all VG, 8mg base with 10% distilled water and 25% flavor. Anyone who mixes VG knows you have to use water or it's like pouring syrup into your cartos and won't wick. The pomegranate didn't work out so well. Using the same default mix the pomegranate wasn't very flavorful, but that is my fault. The new Naturals line of LorAnns will take some time to figure out where the best mix is. I'll probably need some sweetner to really bring it out. Anyway, so far so good with the cartos. The don't seem to dry out, but not quite as strong as with a PTB mod of course. As an out of the box product, I think it's very very close.
