Works, but beware if you have thick hair!
The brush itself was made very well, but for someone with extremely thick hair, it was just too much effort to try to separate my hair into strands that could easily be straightened. The portions of my hair that I did straighten, it took about 3 runs through my hair to get it straight, but it did work. I would recommend this brush, but only if you don't have very thick hair.
