Of all the hair straighteners I have used (and I have used a lot). The Iso Ceramic is one of the better ones. It reaches very high temperatures, which is great for thick, difficult hair like mine. It always gets a nice slick straighten without having to constantly go over the same spot over and over again. I also like that I have never burned myself with it! The outside doesn’t get so hot that it burns your hand. The one flaw in this straightener is that the temperature knob and on switch are on the inside of the straightener which can be hard to get to and may lead to burning your hand if you’re not careful. I enjoy the swivel cord making the straightener easier to maneuver. Being a ceramic straightener it works a lot better than most other straighteners and will always leave your hair smooth and soft. It’s worth more of an investment to get this better straightener.
