I stopped using the two I had in use due to the sudden poor taste from the coils ..they often tasted really nasty. I suspect it was a bad batch as I had the same result with coils from three different suppliers.If I get the urge I might pick up another nautilus Mini from somewhere. Love those little fellers!
Where do you get your coils from?
Have you seen the new Triton due out soon: Aspire - Aspire Triton Has top fill and choice of two sub-ohm or 1.8ohm coils. If there's a good review, I may try one when the price gets sensible!
