I recently bought some replacement coils for my smok tv8f tank. The Q2 0.4ohm type. Looks legit with scratch off on back of box.
The issue I'm getting is that that I taste juice being sucked up via the mouth piece and into my mouth. So as I was cleaning my 8 hour old coil tank pipe I noticed black stuff on paper towel. Is this normal? I'm vaping 70 /30 vapecraft juice. Mod is set at 25W.
The black stuff and also the original issue of juice being drawn into my mouth on every vape is my concern. Thanks.
