2 weeks ago, I bought an aspire premium kit which includes a mini nautilus tank, a CF VV+ battery and 5 coils. I verified that my product was genuine.
I enjoyed the experience. I used 50/50 mix. Until yesterday. The vapors started to taste somewhat strange, so I decided to change the coil. Afterwards, it started to taste like metal and very toxic. I cleaned it, changed the coil again; same problem. I tried all my 5 coils and the taste persists. What should I do? I have read a lot of posts reporting a similar problem. Will buying new coils solve the problem?
