    This straightener didn’t work for my thick course hair. Wish they had one with more watts.

    Some flat irons don’t have temperature control but this one does.

    Unfortunately it’s too good and now my daughter is taking it back to college with her. Very good buy. I would definitely recommend this flat iron.

    Super Light, Super Hot

    I used it for the first time this morning. It heats quickly and stays hot the entire session. Its light weight and I love it so far.

    My hair is straight and soft

    Easy to use and great results. My hair is straight and feel soft and looks pretty.


    Fabulous hair straightener. I can't believe how quickly it gets to the target temperature. I love that it displays the temperature and the auto shut off feature. I never have to worry again if I left it on. This straightener makes my hair so smooth!
