I can't tell any difference from using my CHI straight iron. This glides smoothly across hair without snagging or pulling. Heats up quickly although needs 60 sections to warm back up when I complete a layer of hair.
Overall this works great but the design flaws is what prompted me to return this product. The buttons on the handles outside which cause you to press them when using the iron. I kept changing my temperature every stroke. So I adjusted my hand placement and put my index finger over the little temp screen and then got a BAD cramp in my hand. I could not bare to use this. Altho it did do a good job, i am not a fan. Why would you put controls where your hand is supposed to go??
