Product review (2 stars): Broke quickly
when I had a Brazillian Blow Out and my hair was smooth, this product worked great.  As my hair returned back to its curly state, the Spin Air resulted in a wavy look.  It was hard to get it totally straight because the bristles are not very firm to grab the hair.

Then it just suddenly stopped spinning after about 2 months of usage just a couple of times/week.  The return policy only lasted 30 days so I feel ripped off.
