This dryer is very efficient at quickly drying and smoothing out my hair. I have very long, thicker hair and it normally takes me about 30 minutes to simply dry it. This cuts my dry time down to about 20 which is significant. I also have naturally wavy hair so the diffuser was extra helpful in ensuring this was the dryer for me, though it did not smooth as well as I was hoping for despite using heat protectants and smoothing products during use.

I love how easily the attachments are to operate. They simply snap on and then you're ready to style. It could not be simpler!

Cons? The paint is already chipping off of mine. I'm not a fan of having to pick out very small mint colored pieces from my hair. 
4 out of 5 stars.
