Who designed this??
This tool works well and very quickly to straighten my hair. It heats up very quickly. It is easy to use without burning your hands or neck or scalp.  Unfortunately, the temperature controls are on the handle and it's impossible to hold and use the brush without pushing one of the buttons. So, I am constantly adjusting the temperature.  It is also very difficult to get the same straightening results at the end of my hair as I get near the scalp or thru most of the length. As you brush through the hair, the brush doesn't 'hold' on to the ends. The ends slip thru too quickly once you are thru the bulk in the middle of the hair.
