I absolutely love this hair dryer! My hair dries so fast with it. I did a half and half dry with it and my old hair dryer. This hair dryer dried my half of my hair in 3minutes and 14 seconds and my previous hair dryer took 5 minutes 24 seconds! Hughes difference. My previous hair dryer does make it more smooth compared though, I also had always thought that it dried my hair very quick. I will say with this dryer  my hair does get kind of tangle where it is so powerful. I also really like how easy all of the buttons are to hit! I also dried my pup with this hair dryer yesterday and he did so great with it!
