My hair is quite long and quite curly. I wanted to see how long it would take to straighten my hair and how frizz free I could get it. Overall, the speed and the temperatures on this product are great. I also felt like the guards around really aided in getting close to the hair to smooth it without burning me. What I was left with was a smooth look, some frazzled ends, and a bit of frizz. I don't know that it works as well as other methods, however being sent this product, I can definitely find use for this product, especially for on the go purposes. It's relatively easy to carry around.
