Worked well if you like really tight curls
I liked these rollers.  I would wrap my hair when damp and the curls came out quite tight.  I have medium, shoulder length, coarse hair and the 15 pcs were just enough.  Not comfortable to sleep on which is why I would roll the hair when damp and take out before sleeping.  I recommend if you would like tight curls as I could not find a way to make the curls looser without the hair falling out.  I was looking for a looser wave so I cannot recommend if you only want a small wave to your hair.
