I don't know why anyone would get upset about your question. It's a valid question. Some of us replace smoking with a PV we enjoy and stay with it. Some of us get into vaping and just want to try better and better things to find that elusive "perfect vape". For others it's a little bit habit and a little bit hobby. I'm a little bit of both. I have 3 different types of devices because I enjoy the form of them, but I get a little juice crazy because I love trying new flavors. I do save money, but could save a lot more if it was important to me.
