Go for the Dynavap. It’s the thing that feels the most like smoking to me, but you get the benefits of it not tasting like an ashtray and it being slightly better for your lungs. They’re cheap enough that it’s not a huge financial outlay either.

It’s not the only vape I use and like, but its the one I use the most often.

I’ve found that it gives me a decent skeleton of something that I can then apply to my actual problem, but not much more, and it usually comes with some pretty big mistakes. I was trying to learn Z80 assembly and it gave me a good idea of how my code should generally look, but I did end up having to rewrite a whole bunch of it before I could actually execute anything.
