I haven't been able to find much information on this before pulling the trigger. Just wanted to share with everyone how good this tank is. Compared to my Anyvape Davide and iclear30s it produces much better taste and great vapour. The airflow adjustment is just firm enough that it doesn't lose my setting when I put it in my pocket on my VTR. Not sure what they improved on from the original but this is just between the aerotank mini and mega at 2.8ml and comes with the same accessories (two coils, steel+pyrex glass part, and beauty ring).
