I have purchased lots of cool gear. I could vape for months without buying another thing but------ I like gadgets. So while I am happy with my gear I still buy more stuff and justify it by the fact that I am not spending $15/day (smokes are $10.25/pack in NY). If it is not gear then it is flavors. DIY opens up a whole new spending avenue. You can get a lot of flavors for $20!!! I look at it as a hobby. So I am satisfied that I have a new hobby that has allowed to to quit smoking
