Diffusers - who and how many use them?
Most people here will know what a diffuser is - a small piece of plastic or other material, with many small holes or slots in them, that break up the bubbles/air flow thru the downstem of the hookah.
Now, how many people use them?
Do you notice any difference in smoke? Taste?
Did you go for the "homemade" versions or did you buy one?
If you bought one, where - which type?
If you made one, perhaps post either here or in the "DIY section"
