PAX is a great little thing, fantastic step up from the MFLB. Easy to use/clean.
Fireflys are nice steps up from MFLBs as well. Newer than the PAX.
Volcanos are awesome especially if you plan on smoking with more people than just your brother semi-regularly.
So, I have a question about this as well.
I'm familiar with a volcano type vaporizer and have used it (extensively) when in Amsterdam. never been so high in my life.
What you point out is that something similar exists in pocket size?
What's the high like? Does it have the same effects as regular Joints? Etc...
