Query: The BEST

I love this dryer, which packs a lot of power for a portable. I use it every day as I don't want a bulky unit cluttering my bathroom. I have thick hair and can get it dry with this in under 5 mins.I don't know how much I buy into the ionic thing, but this dryer does leave the hair smooth. The cool button doesn't get terribly cold, though.I took this dual-voltage dryer to Paris and with a turn of the screw at the base of the handle it ran like a dream. Couldn't even tell the difference!
