Like the Kanger AeroTank, the adjustable airflow of Aspire Nautilus really works; Just by turning the lower ring you’ll have four options for adjusting the airflow. Each one is designed to tailor your vape in ways you never thought you’d be able to do with a mass produced glassomizer. You can adjust the drag, as well as the warmth of the vapor, and how much vapor you want to produce. It’s not just some hackneyed thrown together design made to partially work. You will be able to open it up for a very easy draw, or close it down to the point where you think you’ve broken it, or gummed up the coils, or it will remind you of trying to suck up a Frosty through a straw at Wendy’s. However, finding just the right draw is incredibly easy after you’ve accidentally opened it up too much, or closed it down completely a few times. It takes maybe a half a day to get comfortable with it.
