Review (1/5): Completely innefective and a terrible waste of money...
I spent two whole hours getting my whole head put in these ridiculous curlers, not to mention the 30 minutes I spent on YouTube looking up how to use them. Then I left them in overnight.
The result? Zero curls. I'm not kidding... Not even a wave. I was so disappointed. All that time and effort and expense! They were also horribly fiddly to use, with a curling stick thingy that kept breaking in two in the middle whenever I tried to pull the hair through.
Useless. I gave them to my friend's little girl to use on her dollies hair. They're no good on mine.
