So I'm low on cash this month and I need a new coil. There's only one store close to me that sells the Kanger occ coil for the subtank individually. They have both the old square occ and the newer clyndrical ssocc. I can't afford to go elsewhere where they only sell them by the pack. I went to this store not long ago and was about but one of their coils but i got suspicious they were clones when I noticed the wattage rating for the .5 nichrome coil was labeled in correctly (15-30w). I made sure they weren't the SS .5 coils which are rated at 15-30 I think. Thought for moneys sake if get one anyway. Can using a clone/fake coil damage a tank or it's base in anyway before I go and get it?
