I've had a month or more of success with my rebuildables. Great flavor...etc. However, I do notice if I smell the drip tip a few seconds after taking a hit, it smells really burnt. Not good at all. I don't pick up this smell at all when I'm vaping. Does anybody else smell this? Am I doing something wrong? This happens with any of my rebuildables - tanks or drippers. I use kanthal and organic cotton and change wicks daily.
