I love my Nautilus! I have tried just about every Kangertech clearomizer from Evods to PT3...this tank is the supreme topper for those that don't want to learn RBA building and maintenance. The coils are not cheap, but I would say that you get what you pay for. Coming from Kanger heads at about $1.25 each, I am able to get much better flavor, longevity and consistency in vaping with the aspire coils. If you are not sure about the size, aesthetics or cost of the Nautilus, I would recommend either the Aspire BDC tank or Davide Aspire BDC. Both these tanks use Aspire's propriety coil technology that really kicks Kanger's .....
