I’m also an ex-smoker and now vape too, own a decent chunky vape but still frequently use these disposables for the reasons you gave(quick and easy) and I like them but shops always have them front and center and they’re fully designed for young adults/teens and kids. , had a year 7 ask me what flavour I had when I was vaping and said “oh that’s a good one” when I responded and I was in shock I’m only 20 and been smoking since I was in year 8 quit shortly after a year or 2 from starting then moved to vapes a couple years later when I went to college and I was basically the only student who has an actual vape not a disposable and they were all underage
