Product review (5 stars): They work so much better than a regular blow drier
I've owned two of these so far.  They work so much better than a regular blow drier, but they take a lot longer to dry your hair.  So your better off to blow dry a little first, then use this Spin Air Styler.  But even still, plan on it taking a good 1/2 hour or more if you have longer hair.  But if you invest the time, your hair stays cleaner longer (or at least mine does), and it just has better shape, and is softer and smoother.  I invest the time because of how much nicer my hair looks and feels (and how long it looks and feels nicer)  And I can go longer between washings.  I love mine!
