the diffusers are extra, they're not standard. The bongs come in three seperate parts that you take apart. The large bong with the base, the downstem, and the bowl. In most other non-euro and non-expensive bongs, you keep the downstem in the base.

The diffuser is nice, but I started off without one and it still knocked me on my ass. Still, though, the diffuser is very nice and highly recommended.
