My trust chi fell apart recently so I had to hunt for a new flat iron. I've gone through every site that exists I think and still hadn't made up my mind, when I saw this one on sale at a salon and figured I might as well. This was one of the best purchases I've made in hair tools. It heats up lightning fast, which I like a lot, and beeps to let you know it's ready. I have very thick coarse hair and I straightened my entire head in about 15 minutes, that's phenomenal time for me. You can't choose the temp, but I didn't feel as though it was too hot, I pass through at a steady speed anyway, so no burnt hair. I don't use a straightener to curl so I don't know how well it curls, but I would recommend this to anyone looking for an efficient, no frills hair straightener. I use with rusk heat serum and my hair is silky and frizz free, I'm a very happy customer.
