Re: diffuser= easier pull?
i think as you read the reviews you will find much disagreement.
i will tell you, if you have a hookah that bubbles hard, believe it or not, breaking up the bubbles into smaller bubbles gives you the feeling of a smoother flow, not necesarily easier, but smoother.
I've used them before, i have 2 at home, but i havn't used a heba in a few months
