Product review (5 stars): Works well for short hair!
I was nervous to get the 2 in barrell, fearing that it would not work well for my chin length hair.  I'm so glad I was wrong.  It works great for my hair.  I have thin, baby fine blond hair cut chin length with layers only up to an inch higher than my length.  It dries and styles my hair at the same time.  Have not gotten it tangeled in my hair or my daughter's, who has butt length hair.  It gives volume, body and shine.  Some round brushes have made my ends like shaggy and frayed, no such issues here! I have gotten more compliments on how my hair looks recently than I have in my entire life time.  I wish I had found this hot air dryer sooner!  My only concern is for how long the brush will last.  It would be nice if Conair made this to have replacement brushes so you do not have to buy a whole new appliance when the brush is done.  But I have only had this a few weeks, so hopefully I don't have to worry about that any time soon!

UPDATE: its not the brush I should have been worrying about, but the motor for the spin action giving out.  It still works, but one direction is much slower than the other.  I have tried to clear all the hair out of it to see if tangled hair is causing it to slow, but to no avail.
