This curling iron does the trick. i bought the 19-20mm size and it make perfect curls every time. I already have really curly thick hair, but i wanted a change. It produced curls that lasted ALL DAY LONG. It was even decent looking the next day. It take a little bit to get used to wrapping the hair around the stem, but you get use to it quickly. The heat glove they give you doesn't work very well, so i would suggest buying a different one. I bought one from Sally's Beauty Supply and it worked very well. Over all, this iron is amazing. I can't wait to try a different look with it again!

I used the bi-tube for an interview by the beach and my curly hair did not frizz. My hair style held the entire day into the next morning. It was easy to use and it was extremely fast. It gets very hot so please be careful. It took about 5-7 seconds for hair to curl each strand. One of the best investments I 've made for my hair. Love love love it! The price was great because I bought it while it was on sale.
