Hello, I am vaping a boge cartomizer on a switchback right now and i am getting a little bit of a burnt taste... i am getting good vapor production so the carto is not empty so i don't understand why it tastes burnt? 
I've gone through boxes and boxes of 50 packs most of the cartos I used in tanks and I find that you just get a bad one every once in a while or if chain vaping the carto just doesn't have enough time to wick
