Anna, yes, I know the risks of using e-bay. Vendor seems very reputable. I would have been glad to pay more for coils from vaping.com (or element, ect) but was worried the 0.6 ohm coils would run out. If they are in official packaging I'll be happy... if they are loose from some "bulk" pack I'll be ...... off. I had a bad experience with crappy coils from a local shop (for my Evod) and I also had no way of knowing the resistance (I think they were too high) I cursed the Evod, but might get some proper coils and give it another chance.
