Product review (3 stars): First let me state that I have very curly hair ...
First let me state that I have very curly hair.  Type 3 is what it is called.  The brush does dry and straighten, but it leave me hair quite fly away and I can't seem to get the top of my crown very close, so I'm frizzy there.  Also, the brush is realtively soft and I don't think it will stand up for a long period of time.
