So I made the mistake of buying Smok Q2 .4 coils on eBay and although advertised as authentic they were counterfeit. They refunded my money but told me to keep them. I have the big baby beast tank currently. Can I still use these or are they dangerous. I am not concerned that they will burn out quickly cuz they ended up being free but more concerned with any issues it might cause with my mod. Thanks in advance.
