Bio Ionic Universal Diffuser, 1 Count

Fits my blow dryer and works amazing

This diffuser fits my Rusk W8less hair dryer perfectly. I have been using the Conair universal diffuser for years but it continually pops of the hair dryer. The Bio Ionic fits snug and does not pop off. My hair dries faster and my curls are better than before. Highly recommend. It's a little pricey, but should last years and years. It might not travel well because it is rather large. I use a collapsible diffuser for travel, but it does not work as well as the Bio Ionic.

Perfect fit to my bionic 10x.Didn’t get too crazy hot or make the weird burning plastic smell (or burning hair ) that my bed head one did.

I put this on my 30+ year-old hairdryer and it works great. It truly is the universal diffuser.

I bought it specifically because so many people were saying it fit their dryers that were my brands. Unfortunately I got it, took it out of the box to look at it, didn't realize my husband threw away the box when I wasn't paying attention, and by the time I got it into the bathroom a day or two later and check if it fit with my blow dryers I didn't have the box to return it. I have three completely different hair dryers, you would think it would've fit at least one? Nope, it didn't fit any of my three blow dryers. I have a vidal sassoon, conair, and a Revlon. Again, they are all different and different sizes too. It did not fit any of them!! I offered it to my friend, I said just bring your dryer over tho to test it first. Hers (different than all mine) didn't fit either!! I walked it over to three different neighbors and None of theirs fit!!! I am so curious how this is fitting so many other people's? Is there an attachment needed? I am very dissapointed as it was not cheap. So now I'm out the money plus I still need a diffuser and this thing is rather large and taking up space in my drawer because I don't like throwing away anything new. Be careful when buying it, apparently it doesn't fit many dryers at all.

Great quality and easy to use. Got on my hair dryer easily. It does come loose a little, if not positioned exactly right, which is why I give it 4 stars. But besides that it worked well!

I recommend this instead of universal diffuser, I have the 10x bio ionic dryer that I will forever love and this is the only diffuser that works 100%.

The diffuser itself is fine, but it should not be listed as universal. I own 2 hair dryers, and it doesn’t fit either. I have searched in department stores with no luck in finding one that fits. I think they will fit only Bio Ionic dryers, which are much too expensive!

I wasn't sure if it was going to fit on the end of my 1 3/4" diameter blow dryer because the diffuser is 2 1/2" in diameter but it fit well thanks to rubber grips on the inside of the diffuser attatchment. And the adjustable airflow is a great feature.

Gut verpackt - schnell geliefert

good diffuser! adjustable holes for different heat flows. very happy with this product. not sure it's worth as much as charged but definitely a good one.

My daughter bought this on my account, bloody kids, she shows me the package and says it will help her style her hair. I look the exact thing out of the bathroom drawer and say "you mean like this thing?". In all fairness the item is good and works well, but if you have kids and are thinking about it, don't! Add Admiral Ackbar once said, "It's a trap!"

Make sure to measure. For my dryer but not my daughter’s dryer. We had measured prior so we knew this was likely but it’s definitely true.
