This Review Title is Cannot replace actual brush. and the content is: It works fine. Not for very frizzy or curly hair, but worked on my wavy hair. I have medium hair, and not a ton of it on my head. My hair was still not stick straight, but only slightly wavy. Didn't take that much time for me. Maybe 5 minutes.<br /> However, you CANNOT replace combing your hair with this. The brush part is not easy to actually brush out knots with. And some of my stray strands (that weren't attached to my head) got stuck and started to burn. It's also really heavy, and started to make my arm tired quite fast..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
