Product review (3 stars): Gets the job done, but not optimized
The spinning is kind of a cool bonus, but I only use it maybe 1/3 of the time.  Bristles are nice and soft, but almost too soft - they don't catch all of my hair.  My old blow brush had stiff bristles and I could grab all layers at once.  This brush only gets about half of my hair, so I have to use it on top and then underneath.  I don't like the order of modes on the brush - I should be able to push the button all the way up without looking for "high" - instead, the top mode is "cool", so I have to look carefully every time and make sure I don't nudge the button too far.
