I've kind of been getting into pod systems lately. Saw this one in a DJLsb Vapes video. I think it's neat, but Daniel made a good point about a potential problem. Littering. People just tossing dead ones out the window, etc. There have already been problems with this sort of thing, in places like college campuses, with Juul pods. People toss 'em like cigarette butts. That's a people problem though, not a necessarily a vaping problem, but a problem nonetheless.
It's a bit dated, but I really like the Wismec Myjet. It's not much different than most other pods systems out now, but it can be refilled, rewicked, and even re-coiled if you're into tinkering. Has a really nice draw too.
I also like the Kilo 1k, but it's not refillable. I can get about a day out of a pod, and a 4-pack costs $20. That gets expensive quick. Used occasionally like you're talking about wouldn't be that bad though.
