Seven MInutes!
I have a thick mane of varying textures.  My $200 flat iron at the same temperature still takes me 45 minutes to an hour to get the results I saw with this item in SEVEN MINUTES!  I'm over the moon happy with this purchase.  The only thing I personally have to pay attention to is not to hit my ears with the brush.  I used it at the highest setting.
