hey mik, i just picked up your ego tank system. ya got any advice for these for example, cleaning the atty and tanks, what the lifespan are for them, (not tawa either) or maintaining a "clean" atty so to speak. i gotta be honest, what yall have created here is amazing. i've never vaped anything that feels so clean and pure as this, no chemical after taste like cartomizers leave or hassles of dripping, its just amazing. the wave of the future imo be sweet if it could be adapted for the smaller 510 batts for the people still needing the cigarette feel. but anyway i'm rambling...thanks for such a great product.
