To not steal @ek badge every time I wanted to smoke a cigarette while in PlebLab, I started to buy ZYNs but I must say something: they're not as good as other countries' versions.

While they work, maybe too much, they tend to leak and burn their way into the throat... while Italian ZYNs are much much nicer as they don't leak, are more compact and have overall a better pouch design. Maybe VELOs are better in USA.
