I was a bit skeptical considering some reviews I had read. And when I opened the box and looked at the comb, I thought it was too wide toothed to get my hair straight enough. I am black and my hair is very thick and nappy after being washed a blow dried. I had my hair crinkled so I decided to take a strand of my hair and try the comb out. It straighten sooo well. Nice and hot too. I even tried it on my kitchen area. NO NAPS!! I love it!! The only con I have is that the off button is set where you can easily turn it off. But other than that, it's great!!
