Review (1/5): Not for me
I'm a mixed girl with very curly hair, not very kinky or hard to brush but lots of small curls (like a 3C). I decided to try this out to see if it could help my curls shape a bit better but all it did was turn my hair into a frizzy, nappy, unmanageable mess. Ended up damaging my ends trying to carefully brush it out since my hair looked terrible and had to straighten it in the end anyways. Might work better for less curly types.
As for the diffuser itself, it constantly collapses and it didn't want to fit on my fairly standard sized blowdryer (Revlon) without a huge struggle. The silicone has no give at all. Disappointing considering how much it costs while being described as "universal"
