Uh yeah, I was intrigued by the Atlantis when it came out, got one sitting on my ZNA right now as a matter of fact. Let's see about convenience well it only holds 2mls of juice, and the thing is a juice hog that requires all 30 watts my zna is capable of providing for best performance and flavor. So yeah, lotta pulling the tank on and off to fill up the tank. Ok yeah, the Atlantis will pump out a ton of vapor, but then again so do my Odins, Atomic, Zenith, and Rogues on my Reos. And flavor? IMO, while the Atlantis gives decent flavor, it doesn't come close to touching ANY of my bf attys. But that's my opinion.
ETA: looked back at post, and can see the Nautilus and Nautilus minis might be what is being discussed and I have those as well with the bvc heads, have also used those on the ZNA and my 2 provaris, actually have the regular nautilus on my provari and the mini on my provari mini. Those 3 mods are sitting in my vape stand as they have for weeks now collecting dust, because the fact of the matter is that, IMO, nothing I have or have had, approaches the performance, reliability, convenience, and flavor I get from my bf drippers.
