Of all the flat irons I've ever tried, this one by far is the worst. I'm a hispanic woman with naturally wavy hair. I had to go over my hair numerous times before it would fully straighten...and that's because I had it on the highest heat setting. Also, because the bottons take most of the handle, I kept pushing the bottons and had to keep looking at what I pushed and returned it to the setting i wanted. It was annoying. I wish those buttons weren't in the way because I don't know how else to hold it without getting burned. I'm forced to put my hands over the buttons, therefore pushing the buttons and chaning the setting. Frustrating. Plus now it takes me 2x as long to straighten my hair becuase I have to go over my hair so many times until it looks straight. I'm buying another straightener asap.
