Review (5/5): I enjoy this brush
I enjoy this brush. I have coarse long hair that used to be stick straight. In my old age, it is changing textures, and frizzes when someone looks at me the wrong way. A quick spritz of argon oil, run the brush through a few times, and you'll have a shiny coif with a minimal amount of work.
The on/off switch is placed awkwardly, and you have a tendency to turn it off accidentally, but that's the only problem I found!
