@Shameless one thing I have learned helping others start and even in my own vaping is that regardless of what you want it to do...unless the size and shape grabs you then it becomes something that sits in a shelf.
Why not flip through a large vendors site and just see what grabs your attention styling wise. That sound too basic I know but that's what I have found. No point buying the latest and greatest if you don't like how it sits in your hand or where the fire button is or even how light or heavy it is. If you have a bricks and mortar store close, go in and hold them
Then once you have this sorted start to look at the various option and how they fit in your life. Battery life, various types of vaping Vv/VW TC
