Product review (1 stars): Good idea, inferior product!
This is a good idea but the brushes used are inferior. They were never stiff enough to properly catch the hair and after a couple of months the bristles became dull  and slanted in one direction as soon as they heat up, making it impossible to grasp the hair.  I assume this is caused from not being heat resistant enough and now ,after two months use ,it is useless on my medium length hair. A waste of my money!
