The only vape I own that has a session mode that doesn't cook the material is the Tubo.
What about the SBJ? I would consider that a session vape when it has a full chamber. If the chamber is not quite big enough an OG Brick might be what's needed. My OG Brick is capable of huge sessions or .03 gram microdoses.
The instant on-demand convection and large chamber of the Sticky Brick vapes really works well with session type usage. They're the only convection vapes I own that I would label as "session". I don't own a Tubo because I'm broke as fuck right now, but it seems like a good electronic alternative to something Sticky.
Of course the Sticky Bricks are manual and not automatic, so they have a bit of a learning curve and you can't just hand them to somebody and say "hit this". Which can be important in a session with people new to vaping. My solution to this problem, tell your friends to wise the fuck up and start vaping more.
