Been vaping for 2 weeks, so a newbie. Using a smok X-Priv/V12. I found that lack of flavor, juice spitting was a problem and I would varied watts and air flow up and down without seeming to find a sweet spot. Sometimes I would hit it right and get flavor and then it became apparent to me that I needed a constant draw before I could achieve a correct watt and airflow setting. When starting out I was a bit timid and my direct to lung draw was weak and would vary a great deal. I noticed that the Mod would report the puff time duration and I now try to maintain a constant which now produces much more consistent results.
