content: While this dryer did dry my hair sufficiently, I wouldn't recommend it due to safety and reliability concerns. Though it worked for the first 2 years, it began having problems when turned on, often whirring for about 30 seconds before blowing at full power. Eventually this lead to the more serious problem of sizzling smells and sounds from the internal heating wires, causing the dryer to become DANGEROUSLY hot -- as if it were burning up from the inside. As well, the heat-focusing nozzle nearly always fell off while drying, as did the back filter. In sum: don't waste your money on this product. I bought a Hot Tools hairdryer b/c my hairstylist uses one, and I've been happy with it ever since.
