I used an original nautilus (5ml) with the bvc to quit, i loved it so much i'm letting some juice sink in the coil right now to use it againI rarely use drop in coils but I bought 3 nautilus 2s to support and thank Aspire for continuing to support probably the greatest and most versatile MTL coil ever made... How many smokers have gotten free by that coil? I think it is very high number.. and paired w the istick 30, etc... Perfect for the non-hobbyist smoker.
