Im not going to have time to properly talk about my views on the Nautilus X flavour and I want to spend longer vaping on it first anyway, as its been less than a day so far.
I certainly love everything else about the tank. The drip tip normally stays nice and cool, but I have had about 4 random 'ouch that was a hot one' experiences from it.
I don't know about the flavour. Sometimes I think it is great, sometimes not great at all. The vapour is certainly nowhere near as 'wet' as, for example, the triton 1.8 coils. If I close the airflow off to the tiniest hole then the vapour is probably a bit to dry and 'scratchy' for me. The Cubis with the clapton coil that comes with it is my only comparison to other top-flow tanks, and there are similarities in terms of aspects of the taste that people can't agree on, or that seems a bit rubbish. I'm tempted to say I prefer the good old nautilus BVC coils when used with the Plato to this, but I might change my mind later today.
Interesting experience, especially comparing it to the Plato, which is what I'm using now. What wattage have you been using?
