I love this hair dryer, I'm short, so I have shorter arms, the size of this hair dryer makes it far easier for me to use, as well as my teenager. 
I have shoulder length medium thickness hair, and my daughter mid back THICK hair, drying time with the power this compact dryer has shortened immensely for both of us. 
I love the different settings and they're try to their name, hot is HOT and cold is pretty darn cold. 
I couldn't be more pleased with this product over all, what it lacks in size (not complaining) it definitely does not lack in power. I've never dried my hair so quickly on any setting other than high until this dryer came into my life.
