This dryer seems to have the same great quality as my old one. It dries my long hair in under 10 minutes. If I use a round brush, my hair is perfectly smooth, but if I am in a hurry, I can even get a nice look just by using my fingers. It really does seem to reduce frizz.
I have also noticed that while this model dries my hair off very quickly, it doesn't get as hot as the old one did. It is nice not to have to worry about burning my ears, and I expect it will be better for my hair too.
