Not a fan of the hard dryer, except at the salon, and even then it's a bit iffy (got burns from the metal clips once). Soft dryers are great but you still need to connect them to a hair dryer, plus, they can really flatten the hair on the top of your head, even with clips.
My summary is Awesome for deep conditioning, Bad for everyday styling.
