I'm still using my original wick and on 3rd coil. I bet it's the coil, but idk. I've yet to have wicking issues since I got her Rollin
Yeah, vapor production drops when iy is time to change the coil. I change mine about every week. I could get longer then a week with dry burning. But I figure why bother.
Plus rinsing and dryburning takes about 7min. I am down to 3min to wrap a new coil. Times money!
