This hairdryer is by far the strongest dryer I've ever used. Stronger than my stylists dryer! It's like being in a tornado. It certainly dries my hair quickly as it is so strong and also very hot on the high setting. It does give me some added volume which I like but I really can't use it on the high settings. It's very light weight and that is also a plus. 
Would I buy another or recommend it to a friend?? With the high price point I probably would not recommend it or buy another. 
I will continue to use the dryer on the lower settings and Thank you Bzzzz for the opportunity to try it out!
