I recently upgraded to the Istick 30 and Subtank nano, and kinda want to try out a dripper, but do not want to build coils, check ohms etc. Are there any drippers available that take pre made coils? I guess I can wick if needed, but I'm not ready to jump into coil building yet. And if anyone could explain the benefits of dripping over a tank system, that would be great also I know changing flavors without dumping a tank, but any flavor or vapor advantages?
