Review (1/5): Don't waste your money.
I ordered this brush hoping to save some time. After I placed my order I realized it was coming from China, it did ship faster than originally stated. However, the brush isn't any good. I was missing one of the red balls upon opening. The brush also takes a very long time to heat up. Once it finally got hot, it barely did anything but make my hair hot.
I have slightly thick and slightly wavy hair and it was not even close to straight after a dozen brushes. I'd save time by using my flat iron.
Don't waste your time or money with this brush.
