Yeah,
@Stickyblack is on point about the heat soaking. Like I said I don't own a v2. The V1 is quicker to produce dense vapor from a cold start because the heater is smaller.
For me the Z hasn't overshadowed the V1 even though it does perform better. But then I'm the kind of person who saves their favorite shirt and then a week goes by like that and it's laundry day and I never did wear it.
Honestly for just a hit every half hour the v1 or v2 might suit you better. You can for sure heatsoak the Z and use it that way, it just won't shine like it does when you get it warmed up properly.
