I have a problem - years ago I found the perfect mod with the perfect cartomizer for me, I found very cheap replacements from FASTECH, and would have lived happily ever after, except they have stopped making Innokin Itaste vv years ago and though I can still get my EVOD bottom coil clearomizers for a $1:30 each and the heads even cheaper - I notice new mods seem no longer to have the ego type heads they require. I need a new setup - it needs to use cheap replacement coils, it needs usp charge while vaping - it need to be vv or vw, and it needs to be small. I am a very old lady with a fixed income. As I vape unflavored e-liquid my coils last a long time and vaping is extremely cheap for me now. When I see how much people spend and the money wasted on those pod things I am appalled. Please help me find another cheap setup I can live with.
