In the test, I loaded both the CFV and SWIFT Pro with herb and fired them both up to 400. I left the CFV sit untouched for the four minute session, and I took several draws from the SWIFT Pro.

After the 4-minute session(s) were over, I compared the material in the CFV with the fresh unvaped material from the grinder.
The herb left in the CFV without any draws taken remained completely fresh and unvaped. There is no direct conduction vaporization happening in the CFV or SWIFT Pro.
The CFV is available now at Puffitup
