These work well - but they are not comfortable to sleep in.
Unlike some others, I had no difficulty using the product.  I have hair below my waist and I found there was no difficulty at all utilizing the tool or the curler.  They made a nice soft curl that held throughout the day.  From those considerations, this product worked well.  If you have a lot of hair, they can be quite heavy.<br /><br />Unfortunately, these are not the most comfortable things to sleep in.  I wrapped them tightly on my head and still felt like I was sleeping on a lump.  If you have time to utilize these while NOT sleeping, they will work fine.
