This straightener works excellent.... I love it. I have long, super thick, coarse wavy hair. First sign of humidity, I have a frizzy head of hair. Not after using this straightener. I have minimal frizz now (and I live in high humidity Florida). My friend spent $150.00 on her wet/dry straightener, and no one can tell the difference in how these straighteners differ. My hair stays straight for days, appears shinier after use, and leaves no kinks. I highly recommend this product. It's just as good as any high dollar straightener. Don't be fooled by the more you spend, the better the product.
