I am concerned with the effects of EMFs around our 1 year old granddaughter. She likes to hang out when I'm drying my hair and I feel she's not being bombarded if she stays. As to function, it is lighter and quieter than most, GREAT long, heavy cord that doesn't tangle, and a cool button that actually provides cool air. However, there is only a low / high setting with no ability to dry your hair with less heat or less power. I haven't found that to be a problem, but it might be for some people. Personally, I LOVE my new dryer!
