If you're buying original Kanger BCC
coils, they should all taste the same. I buy mine from Sun Vapers, LiteCig, MyVaporstore and they are all the same. I always wash my new
tanks with warm water; you may try soaking your coils briefly in PGA or vodka to get rid of anything that might affect their taste. Also, check your
vaping technique--the coils should always be moist or you'll get dry hits. Do not chain vape and make sure your clearos wick properly. And stay within the recommended 5.5-7.5 watts.
