Re: diffuser, yes or no?
I agree that its probably way cheaper to make yourself, but I bought one recently. I tacked a diffuser on to my shisha order from sahara smoke and it works great. Had to cut it down to make it fit my base but other than that it works pretty legit. My draw doesn't get reduced at all but I'm not sure if it actually improves the smoke. It does make it quieter and reduces shaking to almost none so it was worth it to me
