Well I primed the wick well. Maybe that contributes to no taste.
As for change, I did mine last weekend and it's still going strong. Some have vaped this way for a while but our very heavy VG DIY, usually kill most of our coils in 2 days tops. I won't lie, I'm eager to see if it just makes it to this weekend. 2-3x what I normally get.
I think I may have to track some of this down.
