Before I talk about the function of this hairdryer, let me stop and say that this hairdryer is probably one of the most visually striking blowdriers I've ever had. I love the white/rose gold, then add the clear concentration nozzle....wow! Aside from the looks this is a really nice hairdryer. It has three heats and two speeds, it's not overly cumbersome in weight (it's actually quite light which is good for arm fatigue), and the cord is pretty long which I appreciate since my outlets are not close to my mirror. I have long fine hair but it takes forever to dry and I do think this improved the speed of my blow dry time. I would've liked a setting between the high and low speeds for more precise styling with the concentration nozzle but overall this is a great product and would be an awesome travel hairdryer do to it's small weight and great performance!
