Review title is Daughter likes it, yet only displays in Celsius [SEP] My daughter says that she uses this on the highest setting which is 230 degrees Celsius . We are a Fahrenheit Family so I told her that that is 446 degrees Fahrenheit (our language and understanding). As far as my understanding, there is no way to adjust to Fahrenheit on the display.<br /><br />She  had long semi thick hair that tangles. She thinks that it is a time saver for everyday use. As it heats up in a minute of so and because it detangles and straightens at the same time. She sometimes follows it up with a hot iron when she is looking for that extra flat and straight look.<br /><br />I like how there is an auto-shut off, yet I tell her to turn off after every use just to play it safe.
