i added this on when i bought my QT and its very nice to have when you have a prego wife always fussing about the bubbling noise!! it knocks the noise by at least 75% and the smoke is a lil thicker but not by much!!! i will be getting more to fit the rest of my hookahs for sure!!!

This thing is amazing - Despite the simple idea behind it a plastic part with holes in it, it does the work great - No more funny noise + a nicer experience with the hookah -

Mellows smoke, improves cooling, and makes smoking a hookah whisper quiet - Money well spent -

Just got mine in the mail - Set it up and it's way bigger than I imagined - Great buy

I bought these fully aware it came with 2 in the pack 1 large diffuser and 1 small diffuser - The large one doesn't fit any of my four hookahs, but the small one works great!

Bought it, love it - Smoke is easy to draw, always smooth, very tasty - Hookah is quieter as well, which is a nifty plus - If you're having trouble fitting it onto the stem for the first time, a little water goes a long way - Easily a worthwhile purchase -

when i got this out of the box i read reccomendations to use both filters if you can but i disagree it makes the stem bulky and i had to use more water with both - overall i would say its a great buy -

Picked this up on thurs ... great product great smoke easy draw just great!

Makes smoke super thick and never harsh! Hookah is much quieter which is great if you're talking or listening to music or better yet making a phone call to someone you don't necessarily want hearing the bubble bubble. I only wish you could get two of the same size in the box, but well worth the investment!

I got this one from H-S and slapped it on my 30" twisted sublime hookah. Honestly, a decent product I guess. It comes with both a large and small diffuser but I have only found a use for the large one. Not a bad product, but there are cheaper ones out there that do the same thing.

These diffusers work great, not only do they diffuse the smoke, but they act like hookah silencers, which is nice when your trying to listen to music or watch a movie while smoking. The only problem is that they are only sold in packs of 2, a large and a small. the large ones will not fit down the neck of any of my 3 hookahs, therefore i have to pay 9.95 for one small diffuser. then i am left with one that i cant even use, i wish they would sell them individually or in double packs with the same sizes...

If your looking for a cooler smoother smoke this is the best thing for you. I've owned the ice chamber and that doesn't do much compared to this. And as a bonus it is quieter.

top is silicone. bottom is plastic. big one stretches over the nut on nammor stems with a little effort. breaks up the bubbles as advertised.

I bought this product for my hookah bout three months ago. Its the best thing i have ever bought for my hookah. It makes the flavor so much better as well as quites the noise of the hookah when you suck in through the hose.

I was skeptical that this thing would actually work. But now, after using it, I am a true believer. The little bubbly noises are really amusing, and it actually produces a nicer smoke. I could definitely get along without it, but I am sure glad I bought it. It is a must buy for hookah owners.
