Unfortunately, with me in any Nautilus the coils held by more than two days. And that was quite a costly affair in the long run. At the train technology, it can not have and with more than 9 watts (3.8V) I have not fired.
I have then something cheaper to live ordered fasttech.com the coils and other Aspire Nautilus. Meanwhile, I use only self-winding evaporator ---> Long live the Flash e vapor. 3
My conclusion: The evaporator itself is great, it has a beautiful design, a decent tank capacity and a very good Airflow Control. For beginners who plays already in the top league. However, the life of the coils has been the separation principle for me.
