Review (5/5): I wish I had known about these years ago....
This is a great brush. I have happy hair and in about 3 minutes my hair is tames. I love it. I no longer have to use my straightener. I'm not sure how it is on really super curly hair though. My hair seems to look messy even after I brush it. It's curly in places, wavy in others and the curls go in different directions. This brush fixes it. And it heats up in just a couple of minutes. I love it and I'm glad I bought it.
