Hi, so the GVG is apparently out of the question for europe
They came up with this, the "Vaponic vaporizer", pen size (it actually comes within a pen)
You put the spice into the inner receptacle, onto the mesh, then you put on the outer tube (that has a hole near the mouthpiece to let air in
You heat the outer tube with a torch lighter, which smoothly melts then vaporizes the spice inside
because of the design (I'm guessing), the vapor can not go out.
The vapor itself is really smooth, you have the taste but no harshness (at least at 10mg, the only dose I've tested so far). The spice slowly goes from solid, to liquid, to gas without ever burning.
I never tested the vapor genie, but 10mg in that did just as well as 40mg using the sandwich method (granted, I'm probably very bad at the sandwich method)
I got it for approximately 35 euros (probably about $40)
and it exceeded my hopes by far (to be fair, I had little hope to begin with)
