I've been using this coil for about a month now, maybe longer. I must not have the hang of it but does not product nearly as well as metal coils or Miracle B coil. I've loaded it, and it takes 15-25s of power and draw to get anything going and even then I feel its not hitting right. I could totally be doing this wrong, ymmv.
I keep this tank in case my donut goes out, great flavor just smaller hits.
