Had the same airflow ring issues as it seems everyone else had with this tank (mines SS) and a good disassemble, clean, and re-assemble did the trick been fine since.
My issue, and it seems an uncommon one, is that I'm just not getting the flavour out of it that I was expecting. I know this is probably my build but I'm starting to run out of patience with it as I've tried several setups to no avail.
Tried: 24ga A1 Kanthal, 7 x 2.5mm wraps, ~0.55ohms, cotton bacon prime (fluffed, unfluffed, tighter, looser)
Twisted SS316L pre-builts, 6 x 3mm, ~0.38ohms, cotton bacon prime (again all the fluffing variations)
Both coils have been great in my RDA. Tried at a good range of watts. It's wicking fine (5 hard pulls doesn't dry or burn) seemingly whatever level of 'stuffedness' the ports are. Premade liquid, again lovely in my RDA and mesh tank.
Anyone else had this issue? Turning into a bit of a head-scratcher for me!
