Honestly, I didn’t know what to expect from this product. I was looking for a way to curl my daughter’s hair without heat for an upcoming pageant. I ordered these when my moms old curlers didn’t work and got stuck in her hair. They came yesterday so our trial run was last night. I started with dry hair and wet the comb before rolling each section of hair. Once we were done my daughter kept them in all night playing never once complaining they were uncomfortable. She slept in them even and said they felt fine to lay on. This morning we took them out and I was AMAZED by the gorgeous curls. Wow! I rolled them tight using the skinnier rods because I wasn’t anticipating them working so well. She was loving seeing the gorgeous curls and thought she looked like Goldilocks. I’m blown away by how well they worked and look forward to practicing with them some more. This was my first time ever using this type of roller so I know I didn’t section the hair well but I’m very happy with how it turned out!! Super product!
