For me, it's not a game changer because it was the one thing I'd always been looking for. I know a great many of the fans of the Nautilus love it because it is the first tank system with replaceable coils that actually does a reasonably good job of duplicating the vaping experience that you get off of a rebuildable. The reason that it's a game changer for me is that it actually convinced me, once and for all, that the loose draw with lots of vapor is actually more enjoyable than a tighter draw with less vapor. A week of use and I'm hooked.
What I've found is that I'm getting flavor that is almost as good as the regular Aspire tanks. Bear in mind, ALMOST is the key word. The overall flavor is muted compared to a regular Aspire tank with less airflow. But the overall experience of vaping with no restriction on the airflow and lots of vapor is, well, a bit addictive. I was happy with the Nautilus tank immediately. But now I'm enamored with it. I received a 5-pack of coils today in the mail and so I'm set to vape all I want to on this thing for a couple of months.
I'm just beginning to think I may have a problem. When I'm sitting on the couch in the evening, it is the one I go to. Over and over again. So I've got 7 perfectly good Aspire tanks sitting here. I've got three Protanks, a handful of iClears, a couple rebuildables. And they are all, well, sitting there while I toot away on my Nautilus tank. And I'm wishing I had a couple more of them. Bah!
