Product review (1 stars): Don't waste your money.
The bristles are to weak. They just bend when it spins past the hair. I tried to use without using the rotation (although that's why I bought it) but it won't work as a brush either.
Save your money. Get Art Naturals version (also on Amazon and cheaper).

Sadly I kept trying to make it work and the return window is now past.  30 days is way to short.
