Aspire make good stuff!
I'm a M to L vaper who had been using an Aspire Nautilus tank for years now and loved it. I originally had a Nautilus Mini but wanted to try the 5ml tank in the "big" Nautilus so I didn't have to fill it as often, and it has served me for a long time but I finally got tired of pulling the tank off & unscrewing the base every time I wanted to fill it.
That's when I discovered the Nautilus S2. It looks good, it uses the same coils whether the 1.8 ohm or sub-ohm, the vastly improved air holes offer incredible control over the air/vapour mix AND... It's top loading. You an refill it in seconds. If only they'd made a 5ml version... Then it would've been PERFECT!
