Well I've stumbled upon a new problem, not really sure how to explain but I'll give it a try. 3 out of the 5 Ry4 cartos that I purchased (the cartos that were "defective, leaky") have turned about to be defective I guess. I was just puffing on one, enjoying how great it was, when all of a sudden I got a mouth full of liquid(exaggeration), and then, a really really terrible taste. Not sure what the taste is, almost burnt tasting, but it still produces quite a bit of vapor. any ideas?
