Review (2/5): Fits my dryer but will NOT stay expanded during use
The pros: fits nicely on my dryer and stays put; compact design is nice for travel
The (one big) con: this thing is constantly collapsing during use. I have very thick 3b-c curls, and when I try to get closer to my roots, the weight of my hair pushes the diffuser downwards. This makes it difficult to get volume even when using clips at my roots. I wanted to love this product but this flaw makes it hard to use.
