Review title is Worst thing I have ever bought on Amazon [SEP] I don't want to give any stars to this product.  They were delivered on time and packaged really well.  The following night I decided to try three.  I rolled them in at the top of my head not believing I would sleep well on them.  They did not want to stay in.  I finally did get them rolled in.  Went to bed and they were flopping all over.  One came out in the night - I had to reroll it three times that night.  My hair looked a little curled.  I will be sending these back.  Do not waste your time or your money on these.
