This is my favorite diffuser I've ever owned. I use this with my Jose Eber hair dryer, and it fits snugly in the dryer nozzle without moving the whole time I use it.
I love that it collapses for easy storage. Since it's mostly silicone, you don't have to really wait for it to cool before you store it. This was a great investment.

Helped curl hAir

Just what I wanted... little struggle to keep it on the dryer without it popping off

Measure your dryer opening before you buy this. It's not universal. Read the info in the description to know if it will fit your hair dryer.

I love that it's collapsible and easy to take in his suitcase. It works great
