My other high-end dryer finally died, and I was using my backup hair dryer while doing research before spending a lot of money on a hair dryer. This GHD is terrific. I have long, coarse color-treated hair and when I use a large round brush to dry my hair, I almost don't need my GHD flat iron. The nozzle attachments don't twist or come off in the middle of drying your hair. The air flow is powerful, yet gentle. I know that sounds like an oxymoron, but that's my impression. My hair comes out soft, shiny, and straight! I love it!
