The Chi Straightner is my best friend. I live in the very humid state of Missouri. I can use this straightner with very little product and my super curly hair stays straight all day long. i have tried other straightners with horrible results...such as the instant dreaded "frizz out" as soon as i leave the house! i have owned a chi straightner for 4 years and if i have to replace it i will replace it with another CHI!
