If air flow and flavour are what you seek the Def tank has both especially air flow. Well designed and built. A great tank all round
i love using RTA's and this has won my heart.
Love my high end RTA's and I can happily say I include the Def Tank as part of my collection. I have 4.5mm id coils in mine, easy to build on, fantastic flavour. Well worth the $$ imo
