The InfinitiPRO has extremely fast drying times. Even on a lower heat setting, the dry time is very quick. This really comes in handy when I want to blowdry my hair straight, which usually takes an hour. I'd say that my dry time has been cut in half. That being said, I do not think that this dryer is ideal for curly hair. Even when used with the included diffuser, my hair becomes frizzy regardless of heat or speed setting. The low setting is quite cold, and the medium setting feels like the hot setting on other dryers. I will continue to use this for styling my hair straight, but will not use this moving forward for styling curly.
