I purchased this brush a few months ago from glamourtress and am very pleased with how it did work. I have natural hair and like to go back and forth from curly to straight without using chemicals I used this brush last week and it took my hair from wavy to straight. Do not my hair too straight but got enough to pull my hair into a cute side ponytail. There was very little breakage and there was no problem with the heat. Like this better than an electric or stovetop straightened comb. I used a topical argon oil first then just went through my hair by sections and wallia I had the straightness I needed.
I recommend this brush to anyone who wants to straighten their hair without ant damage. The price of this product is very affordable based on some of the other brushes. And no I have never used anyone other brush to straighten my hair. This is all I need.
