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.

Didn't fit
Super bummed out I thought universal would mean it would fit any hairdryer. I should've read the reviews first just received. It does not fit. Either of my hair dryers not even close. I will be returning it.
