I have an Elchim hair dryer and it fit on it really well, goes on and off super easy, and is a good diffuser. I have super long blonde hair - to my waist - which sounds great except I have some patches that want to curl, some that are wavy, and some that are stick straight (thanks mom). When I want to do curls or waves, I have to use a diffuser.

You can determine how much air comes out by twisting the ring on the end of it and adjust it to your needs. I wish the bowl was just a little bit bigger and deeper, but that's probably because I have longer then average hair. This will probably work for most.

It's a pain to use and takes FOREVER to dry my hair with it. Due to the large size, it would need a very powerful hairdryer to make it work efficiently (or maybe a leafblower?).

I like the idea behind this product, but the execution is poor. It's totally unusable for me.

My daughter wears her hair natural and it's on the curlier side for African American hair. The dryer says it will not blow your curls around, and it does not. You can adjust the flow of air by turning the teeth and this is a great feature for the diffuser.
