Review (4/5): It good but not great.
This does help to straighten out my hair but it leaves the ends frizzier than I would like. I like that I can straighten my hair in less than 5 minutes. It's easier and faster than with a curling iron but the curling iron does a better job. If I am going out someplace special, I use a curling iron. If I just want to do a quick straightening, I use this brush.
