I maintain the aero is better than nautilus. looks better,better volume,better taste. certainly more air flow options. how do you figure the airflow, 3 choices. there is a downside to the aero with a caveat too. the coils last about 50ml. the nautilus last about 100ml. a toss up because the aero coils are $2 and the nautilus $4. I already knew this having had ptii and pt3.
I also maintain, as good as a rba if you build them. the thing is you can have 20 ready to snap in. my rba is done and I have to sit there with a screwdriver. hard to do out in a field where I spend most of my time. yeah,okay kayfun is still better but this is the best option for me.
anyways whatever keeps anyone off analogs! I think for a lot of people the convince wins. until aero and nautilus rba was really the only game at all. really either of them are good alternatives.
edit: nautilus is easier to fill and gives a stronger flavor. it is an exaggerated flavor though. not the actual flavor I expect. the aerotank is much smoother. the nautilus has a lot of bite to the flavor. phil did say the aerotank has better flavor. plus the nautilus loks so ugly. the aerotank looks like a rba at least.
edit again: i don't know if i was doing a fair comparison. the aerotank likes 4.4v on 2ohms. the nautilus likes 5.2+v on 1.6 ohms. still, i think the aerotank tastes better and so said phil. the nautilus looks too ugly as well. the problem with the new aerotanks,mega,mini is they kind of ruined the infinitely variable flow control. they don't look as god either imo. plus with all the kanger dual coils the air goes right down only really warming one coil. perhaps that is why they like only 4.4v. the nautilus also fits any drip tip. the aero-protank not many. you really can't run these on a mech either. you need a dna30 or something. at the end of the day taste still wins. aerotank. the original one though.
