.35 is the absolute lowest it will fire, tho reads down to .2
Just got mine today lightly used from the classies and with a Goblin mini running dual SS coils its firing fine at .28 but Im going to rebuild it tomorrow using some 26 ga kanthal closer to 1.0 to save battery life.
This is the ultimate stealth mod for work when paired with the Goblin mini, you honestly dont know how small it truly is until you hold it.
