Great design, much better than an iron.
I have very fine hair, but it's also color treated and wavy so it gets very frizzy, especially when it's humid. I can straighten my hair and go outside and immediately it's frizzy. I ordered this based on the reviews of other customers. Before I received the brush, I got an email from the company with instructions on how to use the brush. I was very impressed. It does a very nice job on my hair, straightening without making it frizzy. I do like the fact that there are no iron lines in my hair near the roots, I don't know what to call them really, but you know what I mean!!  The brush itself is probably bigger than it needs to be, and I did burn my finger because I didn't hold it properly. If you wear the free glove, that wont be a problem. Overall, it's a great product, much easier than using a flat iron and appears to lessen damage.
