I needed to replace my hair dryer. On high speed, it's not as loud as my old hair dryer. The heat on "high" is not a burning type of heat. My old Conair hair dryer had 1875 watts. On the "high" mode, the heat was intense and it burned my hair.. Although I have long thick hair, I was able to blow dry my hair in less than 10 minutes. I really like this hair dryer. Although the power button is a little hard to operate; however, once you use it several times, it's easier to turn on and off.
