It's a very simple design, no percolators, little diffusion, however you're really paying for the quality and thickness of the glass.

I measured the thickness to be about 6.4mm, which is very thick, glass quality is excellent, the tank joints are superb and the base is very steady, it weighs quite a bit.

Bong has a large, long chamber that holds a large amount of ice cubes, the perfect piece to combine with a quality pre-cooler for diffusion. Great piece.
