FWIW, Re. NETs & mesh wicks:- I vape pretty much 100% NETs, diy ones which are MUCH gunkier than the squeaky-clean Hangsens. It was always a fight for Me to find a way of wicking that did n't clog up quickly.....I ended up using mesh as I can just pull the wicks, burn 'em clean, dry burn the coils, re-insert the wicks & off again. Same coils & wicks in one of My Little 16 clones (squonking) since October..
OK. DIY NET's then, that DIY part I missed, forgot about it as I assumed that all NET's were created equal. My Bad, as they say. So mesh doesn't run differently than other wicking does but, it can be cleaned and reused time after time. Good to know, Thanks yourgurnard.
