I haven't tried it yet, no .. It takes some practice from what i understand.. To close and you combust in the tube (making it no different than a one hitter)

However, given the proper distance and appropriate flame length.. you can have it work very well.. giving you a vaporization and not combustion.

It runs like 20$... So the cost factor is there.

The owner of the THC invented it
BobBong Reviewed by BobBong on . Anyone tried the Oxygen Portable vaporizer? I am desperately looking for a good portable vaporizer. I found this one called the oxygen at vapir.com. Has anyone tried this one or another good one that is a good buy? Rating: 5
