BLOLYO Universal Hair Dryer Diffuser – 1.5-2.36 Inch Adjustable Nozzle Attachment for Curly & Natural Wavy Hair – Reduce Frizz, Enhance Volume – Lightweight Portable for Home & Travel (Black)

This actually works great. Fit on every dryer I’ve tried so far and packs flat.

Perfect. So easy to attach to my blow dryer and I'm wondering why I hadn't used this many many years ago. I never thought I could have curls that bounce and are so defined. This helped me achiever that. I'm still learning how to better style my curly hair but this is a must for curlies out there.

Works just as expected. Great product and value.

I've had this diffuser for over a year and I still love it. I travel a lot and it fits all the hotel hair dryers!! It's very durable and still looks brand-new!

Said it would fit most any hairdryer and my hairdryer was on the list, but this did not fit. Wouldn’t even go over the barrel. I had to buy a whole new hairdryer with a diffuser just so it would fit so this was a waste of money..

Easy to use and stays on no problem. The fit was good for my standard hair dryer. It's great to diffuse curly hair and functions like it's supposed to. Happy with the purchase!

Meh. It works, but it can't tolerate much heat. After using it for a couple of months the little white pads that cushion and help hold the hairdryer to the attachment got lose (maybe from the heat?) and slid down into the diffuser so I had to pull them all off. Cheap quality, but it is usable.

Fit great on my dryer with universal sizing. Our hair dryer is a little less than 2 in in diameter. My Sons love it. Very lightweight but does the job.
