Product review (5 stars): I Love This Rotating Hot Air Styler Brush
Styling your hair will be quicker if you use a blow dryer first to partially dry your hair.  It takes too long to only use the rotating styler brush.  I have only used the 2" attachment and it removes "frizzes" and smooths your hair with a slight curl on the ends.  If you place your hair extending beyond the bristles width, your hair will get tangled.  The 2" attachment does not give you a tight curl.  The length of my hair is about 4-5" past my shoulders.  This is the 2nd one I have owed after 5-ish years my 1st one was losing bristles.
