Size is nice and compact, lightweight, and the air does get hot. However the wide opening on the hair dryer does not concentrate the air flow enough and as a result did not do a good job at drying my hair. I have a chin length bob hair cut that I round brush every morning, and my hair is really fine so it doesn't take much to get it dry. And it does not come with a concentrator attachment so I have to return it. It actually acts like it has a built in diffuser so if that is something you're looking for this might be a good dryer for you.
