Query: Not for over 60's

This blow dryer is not for you if you are 60 or older! It is very heavy and the controls for speed and temperature are difficult to slide up and down. Also, it leaves my hair unusually frizzy. Reviews said that it dries hair really fast, but takes the same amount of time my very old dryer took. Wish I had kept the packaging to return it!
