The InfinityPRO hair dryer by Conair is amazing.  The diffuser is easy to attach and detach and really helps me get more volume from my curls. I love the way the settings are configured into two buttons. It makes finding the perfect speed and temperature quick and easy. My hair gets dry quickly,  leaving me lots of wave and no damage. 
All the best performance in a beautiful package. I'm really impressed with this dryer.
