Query: A time-saver

This is the best hairdryer I've owned!I have long, very thick hair, so I usually only dry my bangs and air-dry the rest; drying and styling my whole head can take more than 30 minutes. This dryer has shortened my drying and styling time to under 10 minutes, fresh out of the shower. It's also lightweight, so my arm doesn't get tired holding it. One thing I wasn't expecting was how great my hair would look and feel afterward; usually, after drying, my hair is coarse and wavy and I have to take a flat iron to it. After using the ionic dryer, my hair is smooth and shiny; no need for the straightener!
