Using ego mega dual coil cartomizer with Johnsons creek red oak tenessee cured (ABSOLUTELY AMAZING) which i am fairly positive is 100% vg (someone correct me if I'm wrong) and i added about 25 drops to my 15 ml. The taste and vapor generation are amazing but i swear my cartomizer is getting really hot! I know the vg being thicker has a harder time wicking but that's why I thinned it. I'm thinking it may be that I enjoy this flavor so much that im chain vaping though! But I'm still curious about everyone else's experience with these warming up quickly
