Yes, you read that right. My Heracles RTA2 still has the very first build and wicking I ever put in it. I have not opened it once since the day I got it. Tastes great and vapes great. How can this possibly be? I'm thinking maybe I just like gunked up coils and antique cotton or something. I don't even remember the build I made for it now. All I know is it's .22 ohms and I've been vaping Lemon Twist in it at 90 watts on my Procolor since October.. Near as I can tell, it hasn't even changed in vape quality and flavor since the cotton broke in.
