Product review (5 stars): I loved it. Eventually the battery wouldn't take a charge ...
There used to be a tool called the Revo Styler.  It was a revolving brush with a re-chargeable battery.  I loved it.  Eventually the battery wouldn't  take a charge and it had to be thrown away,  It was no longer on the market.  This is the first thing I've found that works as well.  My hair is smooth, full nd shiny with the Conair spin air rotating brush!  What's even better, it takes half the time to do my hair.  No flat iron or curling iron needed.  This means less heat damage to  my hair.  I highly recommend it!
