My lady has one of these. She got it from a local head shop. It's pretty smooth for a non-water like piece. To get the tornado effect you have to take a decent rip. The headshop we picked it up from said it's made on the west coast in Oregon.
It's definitely worth a try, but if you're into collecting glass, it's a great addition.

O, ic. I was going to say you'd have to have some weird sucking pattern to make smoke swirl through a normal piece.
