I do not know how these things are not the HOT TOPIC in all women's mags, female social circles, Facebook, twitter, etc.  I have very thick, coarse Asian/German hair and have a heck of a time managing it.  Ponytails can start to hurt my head eventually since I have to make them so tight to keep the hair in one place due to its weight and volume.  THESE THINGS ARE MAGIC.  I have hair that is down to my chest and when gathered is the equivalent of several ponytails of typical female hair.  I put a high bun in when I got these puppies- and it STAYED PUT.  No hair elastics, no product, no 100 regular bobby pins, no slipping of the elastics as bun loosens over the day- BUY THESE ASAP!!!! I used 4 in my bun, just be careful when unscrewing that you do it in the reverse order of how you put them in so that you don't damage the spin pins or yourself.  I haven't touched my hair since 7am and it's past lunch- this has never happened before.  Very happy customer!
