"You don't have to spend the $100 for an flat iron when you can buy this one!" one customer wrote. "This leaves your hair SPEC-TA-CULAR! And you can do curls with it as well. I have dry hair and with previous flat irons that I tried, damaged my hair more until my beautician recommended this one for me. Leaves the hair soft and shiny."
