Love it! Exactly what I needed!
This diffuser fits perfectly on my BIO IONIC dryer, has extended fingers that works great for my long hair and feels great on my scalp. The diffuser also has customizable vents to better control the airflow for my hair needs and helps me minimize hot spots in my hair. It's well built and I love it! ...

Loved but does not fit my amika dryer
I was so happy seeing someone review that it fit with their amika hair dryer. I got it hoping it would. It did not. I used my friends hair dryer because I needed dry curls for an event. It worked wonders using that one, but sadly not my own.

Fantastic Diffuser

It's the best diffuser I've ever used!
incorrect product description
This item says it fits a 2.25" diameter. My blow dryer diameter was just under 2.25". When I received the diffuser, it was too SMALL!
Perfect fit and function
Fit my Amika hairdryer perfectly and works well in allowing my slightly wavy fine hair to do it's natural thing. I have wavy underneath hair and straighter top hair and with this, I cup it in sections and it's the same all over. Just what I wanted.
Terrific Diffuser
I searched all over looking for a diffuser. This one works very well. It fits nicely over the end of my dryer which is about 2", due to its stretchy cuff. The longer prongs really do help define my curls. Excellent purchase.
