I generally don't write reviews, but I was blown away by this hair dryer (no pun intended). It's truly an engineering feat that this hair dryer possesses the characteristics of being both powerful and quiet while simultaneously having an EXTREMELY low weight. (This last characteristic became important to me when, at one point, while using my SuperSolano, my neck suddenly went out while drying my hair one morning - not fun!)Upon my initial use of the CHI Rocket, it seemed that it had very little power, but before I knew it, my hair was dry AND smooth (my hair type is wavy and very long), and I wasn't working very hard to get it that way; I would surmise that it cut my drying time by 30% - 40%. Also (and possibly more importantly), upon waking the following morning, my hair still looked great - and I usually have to wash my hair every single morning, without fail. Given that this time of the year is the most humid, the results of my "morning test" become even more impressive.For the Amazon price, this dryer seems that it would be a good investment, given it is a tool that I usually must use on a daily basis (saves time,time is money, and all that jazz). I generally am extremely skeptical about a beauty product's or tool's scientific claims (ion technology, biochemical therapeutic claims, etc.) given that my background is in the sciences, so I know that half of the claims are false or can be achieved by a $3 product/tool competitor, but someone knew what they were doing when they designed this puppy, so I'm more apt to believe that it's better for hair health as well; what is definitely true is that cutting drying time will save some hair damage.Great product. Fingers crossed that it lasts!
