Ok Jack, as a test of it's functionality and acceptibility into society, go to your local police station, stand at the front door, no closer that 25 ft, and smoke away. As plenty have pointed out, this is going to raise an eyebrow or two.
On another note, pipe smoking is centuries old and i kind of think the whole look and feel of this unit severely takes away from the heritage and general idea of pipe smoking. It has long been a fact that briar wood, not stainless steel, is the material of choice used for complimenting your pipe tobacco. I'm not sure how well SS will season.
As they said on SNL, "Dude, you put your weed in it."
However, back in my less responsible days, this thing would have been the shizzle!!!
