Best I have used [SEP] I have ordered and tried many heatless curlers (including that octo-curl headpiece) and I keep coming back to this one. It's definitely for long hair. The wrap is foam and denser and wider than most- SCORE! Much better for larger curls.  I was afraid the foam wraps would be uncomfortable. But that's the price you pay for larger curls so it's FINE with me, and I will sleep in it. It also comes with four satin scrunchies- two large to hold  the ends when it's done, and two small for wrapping your ends. I don't quite understand the prickly clips for root volume. If I'm being completely honest, one of them fell off the counter and stuck to my slipper. I didn't find it until I went to bed. Obviously I didn't miss anything.
