Review (4/5): good starter/trial brush to see how often it will be ...
Does help the process along with straightening, as with other reviewers, agree that power button is in the wrong position, to help remedy this I held the temperature button during straightening the hair. Also as stated by others, you do still need a flat iron especially to get the roots. But it does help the process overall, good starter/trial brush to see how often it will be used, then will likely upgrade to one with better button placement.
