I'm a sub ohmer for life. I love my ADV to sit between .17 ohm and no higher than .25 ohm. Something about that thick warm vapor that tastes so good and is satisfying to me. Some of you guys might want to download vapers toolbox, great free app if you understand what you're doing but it can help noobs too. Just remember use a multimeter or ohm reader after you build it.
