So, I have this clearmizer (no idea what brand, or even how to spell that word, honestly. Kind of new at this) and an Ego CE-4 battery. Works great most of the time, but recently I've been getting a nasty taste from it, like you would get if you were trying to vape from an empty/low-fluid cartomizer. That kinda nasty, burning taste that stings in your throat and mouth. I've tried cleaning it, once with just water and then with water and alcohol. Both times it worked for a little bit, but it keeps coming back. Am I using it wrong? Do I need a more rigorous cleaning? Does my clearmizer just suck? I've had to buy two of this type since the first one broke on me (the connection to the battery failed), and it's a real possibility that it's just a piece of crap. If it is, what can someone recommend for a better one?
