Perfect size for slightly larger blow dryers. A nice big bowl that fits a lot of hair in it, I have long thick hair and it’s one of the better ones I’ve ever used. I also like that you can adjust the airflow. It does get hot during use, as has every other diffuser I’ve used has- so be mindful of that.

I didn't really know what to expect out of this odd looking thing but since I have naturally curly frizzy hair that can't or won't be controlled. I wanted to check this item out and see what it's about because if it could take the frizz and kink out of my hair it can help anyone.

My hair is just below shoulder length and processed and I use a variety of unnatural colors at any given time (mermaid- purple, pink blue, green, etc..) and I straighten so you know my hair is pretty fried. I normally use a bit of argon oil as soon as I wash to tame it down before drying but for this test I did not.

It fits 3 of my 4 dryers (newer and smaller ends- under 2 inches) with no problem and comes right off BUT it doesn't fit any of my daughters' dryers- theirs are all older and have ends that are wider than 2 inches. You will not be able to use this item if the end of your dryer is 2 inches in diameter. Actually, it's slightly less than 2 inches so at a full 2 inches you might as well forget it.

It does stay on until you want to remove it and it's not big and heavy- it's very lightweight..
