Yeah the ear stuff. I haven't tried it yet. Today I haven't filled my P3 Kabuki all the way. I think it might be helping. I'll try it on the 510 version later. I been vaping Sweet tobacco all day then switch the Vanilla Tobacco later. I maybe getting tired if Vaniila in the Kabuki. I think it makes it stronger in the Kabuki then the kayfun 4.The EAR stuff????
