Hi, I have really been enjoying the locking Artemas tank. I have tried other devices but the carto tank is the easiest and most effective device I've tried. 
I have been using. 1.5 ohm dual coil on it. It was suggested to me to try a single coil because it produces more vapor and saves your battery.
Any input?
