Review (3/5): Too collapsible.
I have always used a deeper cup that I could actually get more hair into and hold up to my scalp. But there are none currently on Amazon so I went with this one. Figuring the collapsible travel part would be a bonus. However when I place this under my hair and lift up to scalp it collapses against my head. I will probably keep this one for travel but keep an eye out for one that won't collapse against my head.
