I've only been doing this for a couple weeks and I have just been trying all sorts of different flavor juices. I have a smoov and I have noticed that some juices seem runnier or drip. Of the ones I've ordered it seems cappucino, a few cafe ones and a white chocolate. Am I doing something wrong or are they intended for different types of e-cigs or cartos. I havent been able to really even vape these flavors, it drips, I blow it out and I hardly get any vapor. maybe this is a dumb question but if anyone can help thatd be great.
