I am more into rebuildable atomizers, but I've been trying to get into tanks lately and I've had a couple tanks but either they leak like crazy or I fuck them up and mess up the OCC coils. I have the kangertech sub tank mini and I was wondering if you can use that on unregulated box mods or is it just for regulated box mods. Also are all the kanger tech OCC coils interchangeable with eachother. Thanks in advance!
