Love it!
I love it.  It's a flat iron brush, basically.  It works well and fast.  It won't get your hair stick straight, but it definitely takes the frizz out and does a good job of straightening with a little body.  I was hesitant about purchasing but glad I did.  I'm Caucasian with hair that falls to my mid-back an average hair thickness and coarseness.  When I let my hair dry on its own, it curls up but not enough to look pretty..wavy/frizzy.
