Quick question.... How long do your coils last and or how often do you change out your set-ups? I have been 2+ weeks on mine and it still is the same as day one. I am using 28ga w/ 3mm silica wick coming in at about 1 ohm, using an Igo-L on my Natural in 18350 mode. I only vape one liquid and think that might be part of the reason. I guess I am lucky in that regard finding a favorite all day, every day, vape....regardless of what device I am using, which might be another part of it. I do switch between this set-up and my kicked Vmod XL through the day. I find the Natural set-up to be a little harsh in the AM and vape the XL for the first few hours of the day. Just trying to get an idea of what some others have experienced....
