Here are pictures of the same coil and wick from aspire bvc. I have been using it lightly for a week. I vape about 1.5ml a day; chain vaping for 3-4 15min sessions a day. 4-6 sec drags on 4.2v (1.8ohm). It was still working fine when before i took it apart, but my concern is the burnt portion of the wick. Is this normal? and would i be able to continue using it or will it cause health problems vaping on a burnt wick?
