This Conair Pro Dryer is amazing.  It has all the settings I need to make my hair look great without damaging it at all.  It comes with a diffuser and a concentrator attachment.  I really like the cool shot button which helps me lock in a hairstyle and is good on days when I feel like my hair needs extra hold.  I like to use the cool/medium setting while my hair is recovering from being bleached.  It works so well and my hair is very smooth after using this dryer.
