Flavor with 0.7 Ohm coil
Smooth atomizer base makes top-fill mechanism more difficult than it should be
Small tank capacity
Flavor with 1.8 Ohm coil
I'm liking this little tank. My philosophy of use is for this to be my "going out" tank so I don't have to be chucking clouds in a crowd of other people trying to enjoy their night, and to pair it with an iStick Pico for portability. The flavor got much better once I tried it with some 70/30 juice as opposed to the Max VG I usually vape and I've got some 60/40 in the mail specifically for this tank. I personally found the 1.8 Ohm coil almost unusable with little flavor and minimal vapor production. The 0.7 Ohm coils are great, though. I can get two days battery life with this tank on a single-battery mod, and a full tank of juice will last me a couple hours out and about so I don't have to be chained to a bottle of juice.
My wife and I are MTL vapers (primarily) and have been using the Nautilus and Nautilus Mini for a couple of years now. When I saw this re-do, I thought I'd take the plunge. It's a very nice design, top fill, has two coil options and comes with a 1.8 ohm clapton and a .7 ohm coil. I'm currently using the .7 that was pre-installed in the tank. So, I threw it on the Wismec Predator I just got from VapeNW and filled it with some yummy juice, put it on power mode and cranked it up to 12.5 Watts and WHOA! This is a flavor machine and is a large step up from its predecessors (IMO). If you are a MTL vaper, you will be very happy with this tank. The airflow control is very smooth, but it lacks the "detents" on the previous Nautilus models. The airflow is five holes graduated in size and I'm using it with three of them open, for the draw I prefer. It has a removable drip tip. It comes with a bunch of extra O rings, a 1.8 ohm clapton coil (the .7 ohm is installed in the tank), and a spare glass cylinder. It looks very cool sitting on the predator. It also comes in several colors, but I usually prefer stainless.
The only, and probably biggest CON is: It only holds 2ml of liquid. I will be spending COUNTLESS trips to the pantry (my vaping storage closet) for a refill. Great for extra exercise, but I'd love to see it in a 4ml version. It also would NOT be good for long road trips unless you have a co-pilot to fill it for you, or plan on frequent stops to refill. For the flavor it produces, though, it is TOTALLY a rad tank! I highly recommend it! I also highly recommend VapeNW!
