Pretty good after all!
My hair is curly and I love making it straight.  My Chi Air flat iron is wonderful, but takes quite a bit of time to straighten my hair.  So I thought that having a straightening brush would help touching up my straightened hair in the mornings or after having it in a pony tail.  The summer is especially testy as I can't stand to put all of the time into straightening and then get in the pool or walk out in the humidity. My niece, who is also my stylist, said that they had used one in her salon and no one was very pleased with it, but she knew that I was interested in trying one and encouraged me to do so.  So after researching and reading reviews, I came across the RoseMyst brush.  At first I tried just blowing my hair dry and then tried to straighten it with the brush.  That didn't work very well, because it didn't get the kinks out at the root and didn't produce the smooth look that the Chi does.  But I kept experimenting and realized that it really worked well if I just let my hair dry naturally without any hair product and then straighten it using the brush.  And...it works quite well to touch up once my hair has been straightened by the Chi.  My hair has a more course feel to it using the brush, but it also doesn't tend to curl or frizz once it's done.  So...I am very pleased with my purchase now that I have figured out how to get around the limitations and work with my own hair type and convenience.
