Hey Mimi, welcome to ECF (belatedly). Congrats on switching to vaping that is fantastic! I agree, vaping is so much nicer than smoking... Now that my cigarette detox is over.
Everything I learned about vaping, I learned here. LOL, before you know it you will be handing out advice like candy. I'm glad you are enjoying your older gear, vaping has been working since it began, so absolutely nothing wrong with that! Most of my more expensive mods are older, purchased used, etc. and while I enjoy some of the newer offerings, well variety is the spice of life.
