This hot tools probably works great on longer hair.  Mine is too shot for this product (its down to my shoulders).  It gets very hot very fast so be careful.  I liked the long, easy swivel cord, makes it easy to wrap your hair around the barrel. Also the end of the barrel has a safe non thermal tip so you don't have to worry about burning your fingers. The hair is held tightly and there are even spring clips that are added in the package.  I am going to give this to my daughter who has really long hair. The curls will be better and more pronounced with her hair length.  When I used it, my hair just had body with only a little bit of curl.
