I use cotton wicks so, never dry burn with any wicks in place but, I will dry burn the coils if they are gunked up and a vinegar soak doesn't quite clear them. With unflavored 100% PG, yes I can get 14 days before even cleaning them but, with anything else it varies from 1 to 5 days before I have to clean and, again some juices need the dry burn to get all the gunk off the coils.
Saves rebuilding quite so often.
I also have a couple of juices I drip only because 1-2 mils gunks the coils to the point of them needing cleaned.
