Review (5/5): some were quite good, but none of really makes my hair look ...
I've had many hair straighteners and smoothing/curling brushes in the past; some were quite good, but none of really makes my hair look as good as this one. I don't even have to use my hair dryer anymore (my hair is fine, and dries quickly). It was a fine curling brush/hair dryer (https://www.amazon.com/Revlon-Shine-Enchancing-Hot-Air/dp/B00022WA9K/ref=sr_1_2_a_it?ie=UTF8&qid=1470675698&sr=8-2&keywords=revlon+hair+dryer+brush), and I liked it a lot; but this is far better, and I get lots od compliments lately on my hair.
If I just use the curling brush, my hair looks good for a day...great for when I'm kind of in a rush. But when I take the time to use the straightener, my hair looks great until next time I wash it. My favorite look is when I straighten it, then clamp the plates together to make the curling brush.
I still haven't figured out the "3 in 1", I only know of 2...but it is a great duo.
