I have most of the name brand tanks kind of a hobby and so far this melo has the best draw of them all. What makes me wonder is why this tank is not getting the attention it deserves could it be the cheap price? I used a RBA same one I used on the aspire atlantis and project sub-ohm silverplay and it worked as good as the replacement coils that came with the melo. Anyhow I"M more pleased with this tank than all the others kind of surprised me.
