It's really worth ZERO stars!!
If I could have given 0 (zero) stars I would have.  I played around with this piece of junk for almost 2 hours trying to do a chignon.  When you put your hair into the clip, as you pull it down to the ends of your hair, it turns and flips on you so you are fighting to keep the miniscule teeth of the clip on your hair the entire time.  IF (and that's a big IF), you finally get it into position so you can roll it back down towards your head, as you start rolling, your hair starts sticking out of the clip and by the time you are down and ready to twist it closed, you have very little hair in the chignon and most of it sticking out (assuming you did not get it tangled in your hair).<br /><br />I tried wetting my hair, applying a light gel, everything to keep my hair together, but nothing worked.  I wear my hair bone-straight, same length all around (even cut, like a bob), thick and falls about 4 inches below my shoulders.  I even tried sliding it down to the end, but leaving about 3 inches of hair beyond the clip, and tat still didn't work, the clip still did not roll the hair down properly.  These were my personal experiences with the clip, other issues I had with the product:<br /><br />1) Instructions are ONLY written in Kanji (Chinese) letters.  The least the product vendor can do it slip in an English (or even Spanish) translation when selling the product to US purchasers.  I should not have to have my laptop running the video while I am trying to do my hair.<br /><br />2) The clip really is made of a cheap, flimsy plastic, so it has absolutely no ability to stay straight on the hair and not bend/flip.  If you have thick hair, avoid it, since you will have trouble getting in position to even start the roll down.<br /><br />Overall, the clips (I ordered two of them) went back very quickly to Amazon (and yes, is there a reason why Amazon ships two flat pieces of plastic in a box designed to hold a book? They could have been shipped in a manila envelope...thereby saving the customer shipping charges).  This product has absolutely no quality and considering the pirce paid, iyou would be better off going to a "dollar store" and getting something for 99 cents!
