I just got the Atlantis and for people who are not used to direct "lung" hits, you might like it, you might dislike it.
For high quality eliquids, doing direct lung hits brings out some serious flavors. I couldn't get all parts of the flavors using the Nautilus mini. It is bold and you get a subtle but lasting aftertaste. Again best to do this with a quality eliquid
If you like tobacco flavors or are just not into lung hits, you will need to set it on the 1st or 2nd smallest aireholes. I personally don't like the smallest one bc the flavor is too concentrated for my liking. And will need to change the massive drip tip to a very small drip tip (smaller than nautilus mini). Like from the mini protank kind of drip tip.
Then you can get sort of a "mouth to lung hit" (though still more directly to the lung) . The kind of hit you are used to with the Nautilus Mini Bvc, but better and easier pull.
So with some minor tweaks (changing drip tip, airhole) , it is a versatile tank. Either way, the pull is mad easy, smooth , nice to bold flavor, very good to extreme vapor production capability. I definitely recommend it
