Re: do Heba Diffuser actually work? worth $10 ?
I use one.
Made a huge difference in flavor and cloud density when I used it on my cheap chinese pipe. HUGE DIFFERENCE. Much stronger flavor, cooler smoke.
KM is another story. There is a slight difference in flavor... Very slight. If you pull the stem and pop it on mid-session you will notice a slight change in the flavor. Mostly it seems to bring out some of the subtleties of the flavor. No difference in cooling or clouds from what I can tell.
I do find it very handy in quieting the hookah when watching movies, which I do all the time. Very handy indeed.
Basically, it turns a crappy hookah into a usable one.
