Re: KM and a diffuser.
i have a similar hookah, same line, different design, but my stem is like all others in that line.
I have a diffuser on it.
It works like its supposed to.
Fairly easy to get on, i cut it, two little slits, and it fit better than OJ's glove
i actually have both sizes on small inside the large
