Product review (5 stars): Like having 3 hands
Spin-stylers are a wonderful invention, unless you already have 3 hands, which most of us don't. However,  there's a slight learning curve. You have to keep the brush moving down the hair strand as the brush is rotating. If you don't, it will wind up your hair very tightly, very quickly (which made for an instant of panic the first time it happened to me). In that case, you simply stop pushing the button and switch to the other button which rotates the brush in the opposite direction and unwinds your hair just as quickly. You have to keep in mind that YOU are in total control of the brush. The appliance actually comes with two brushes. I use the smaller of the two because my hair is only chin-length. It gives nice body on top with large, soft curves on the ends, perfect for today's unstructured styles. I also own a Conair blow dryer, which I use to get my hair mostly dry before using the spin styler. I've had good luck with other Conair products, and so far I like this one a lot too. If the past is any indication, this product will last me for years.
