Re: Heba diffuser - whats your take on it?
I haven't used the "official" one, but have made several of my own. For smaller hookahs, they do seem to help effect the smoke, but for larger hookahs they only seem to deaden the noise of the water. And I like the "bubble-bubble" of my hookahs!
Plus, from what I understand, the Official version of the diffuser is supposed to be REPLACED somewhat often as it appears to asborb things (smoke, nicotine, ect) into the plastic.
If you want to experiment w/ diffusers, make a DIY version - see the How To Section - cheaper. Basically the cost of a can of Guiness or a pack of ping-pong balls.
