I have very curly hair and blowing it dry without the use of a flat iron can leave it frizzy. I have tried every hair product before blowing it dry and it still doesn't do the trick. I have purchased the best hair dryers and the best brushes, and it still doesn't do the trick. The CHI makes my hair silky smooth every time. I like that it has several heat settings so I can customize it. Because it can go to 450, I can straighten all my hair in under a minute if I am in a rush. Unlike other flat irons that I have used in the past, this one does not snag my hair or break it as I move it down the strands. My one suggestion would be that since it gets so incredibly hot, you should use a heat protecting spray. My personal favorite is by a french company called Davines, but you can find these protecting sprays in the drug store for less money as well. Durability I have had this CHI since 2008 (7 years). My best friend has had hers longer and it just broke. Overall, I would say that is pretty good quality!
