There seems to be more and more smok coils that Iam no longer understanding. I wanted a coils for my baby beast tank. I usually get the q2 0.4 ohm coils. They didn't have it. There was a q4 0.4ohm pack of 5 smok coils that I never saw before but it said it was for tf12 prince and v8 baby. I thought it was for my tank. When I received them they do fit my tank but something is really wrong. So did I buy the wrong coils? It's upsetting because it cost so much to buy coils online now and I hardly have any money. And it's such a pain to do with all the new mail issues. And a lot of my vape shops online are gone. :-(
