There is no doubt that Aspire Nautilus is really a fantastic atomizer, especially for its tasteful flavor. Maybe for those experienced vapers, the first aspiration is to rebuild its atomizer coil when they get this nautilus tank. But this tank seems to be so different. Generally, Nautilus Tank is not suggest using on a mechanical mod because the positive of Nautilus atomizer is a resilient electrode, easily causing hidden risk. Rebuilding coils on Aspire Nautilus is not recommended because its inner structure is so compact and easily causes short-resistance. Even you succeed in rebuilding your won coils on Nautilus and still you can not enjoy the same taste as the original Aspire Nautilus coils. Happy and safely enjoy vaping on Aspire Nautilus.
