Another happy owner here. Being it was my first hookah purchase, I think I came out on top. The original stem that came with my 36" wasn't quite airtight, but the replacement was perfect. Also the gromment on the replacement was tightly fitted on the vase, and required no further adjustments. And about the vase, oh, what a beauty. The stem is amazingly good looking. Even the trays were easy on the eyes. The drawbacks on this hookah has already been mentioned: the down stem. The bowl, while not bad, isn't good either. An overtly average bowl on an otherwise stunning combination. A Smiley bowl I got from HC quickly fixed that. Both the original stem and the replacement stem I received has a gray plastic diffuser added to the bottom of the stem. This diffuse does it's job of breaking up the smoke well enough but added nothing to the overall length. There is also a slight, very slight air leak at the blow out valve (not the bearing but outside the valve itself.) Not enough to affect anything, but I thought I should mention. It was really down to the wire when I first considered between the AF and the Stargate. But when I consider the aesthetics, I think the AF is the most beautiful hookah on the market. It looks like a supermodel, and smokes like one too. I've taken a point off for the stem lenght and the average bowl. 9/10
