You are not supposed to be able to screw any atty/carto/adapter all the way into the Darwin. There should be a gap of just about 1/8 inch between the bottom of the atty and the top of the threads on the Darwin. This was done on purpose for airflow. I fit is screwed in far enough to be able to vape, then it's far enough.
Yea, I've never cranked it down. Essentially I get it down enough to where it hits.
The problem is that where it hits now it will come out with the slightest wiggle - doesn't mean I'm still not using it though!
Hope everyone's night is well. I think I'm going to try and knock out some Chemistry homework. Who said going back to school in your mid/late twenties was good idea?
