Great Customer Service
I've used these for a while now.  Although I like the fact that you get a variety of sizes, I don't like the fact that they do not bend and hold very well.  I have other ones that are bend and hold my hair better than these.  My curls don't come out as great.  Although the product did not work for me, customer service was awesome and very responsive.  Therefore, I am giving them 4 stars for customer service.
