Does the job so thats a plus, you have to take into consideration the type of hair you are going to use this on . I first tried it on my hair which is about wavy kind of thick and medium length and although it did not produce silky smooth results as the box read, it did manage to straighten it enough. On the other hand, I did try this product on my moms hair which is twice as thick as mine and really curly and sort of hard to tame but with sectioning and brushing before using the actual paddle brush it did also manage to straighten the hair just enough. I went over half of the head that was straightened with the paddle brush with a cofia flat iron and it looked way better than the paddle brush alone. That being said I did return the product and will be sticking to my flat iron for smooth silky results!
