I am currently running a smok magneto with a .28 build in a plume veil and a 18650 Sony vtc4 2100 mah. The flavor is great it's just not producing the vapor it should. FYI this is my first mech mod. I've already had problems with the spring collapsing in the top connection pin. Took me 4 hours to figure out that problem lol not liking this mod more everyday.
