Review (3/5): Great way to dry hair without drying out hair.
It dries hair better than my other non-collapsable diffusers. It dries my hair quicker and without drying out my hair, so my hair still looks moisturizer. The only thing is that I feel it collapses too easily. The slightest touch of my head and the entire thing flattens. I don't think that's normal with this type of diffuser. Maybe mine just wasn't part of the lucky manufactured batch.
