I just bought this today from their walk in store and using as I type.
This is the best "pipe" that I have used to date and after 25 years that is saying something. This larger version is slightly bigger than I expected (certainly not stealth) but forgiven due to the quality of the smoke.
The smoke composition comes out somewhere between a conventional pipe and a vaporizer. There are three small holes that allow some of the flame to get through to your product, but also it is being heated up by the metal itself. The smoke comes out surprisingly cool, so the helix structure within is clearly doing it's job.
