The T3 Featherweight is a salon quality hairdryer that has a Tourmaline ceramic heater for superquick drying. The T3 dryer weighs only 13 ounces so your arms don't get tired while you are using it. At 10 feet the cord length is great. You can dry both sides of your head without having to turn around! The motor is quiet compared to the drugstore variety hairdryers I have owned before. I've noticed that the airflow from this hairdryer is much less forceful as well. You have more control over styling your hair as it is not blowing all over the place. The T3 is advertised as drying hair 60% faster than usual because "Tourmaline negative ions break down water molecules into tiny droplets that evaporate faster and at the same time the far infrared energy heats the hair not the air". I'm not sure about the science behind this claim, but the T3 does dry your hair faster. The faster drying is mostly because the air is HOT! There are two different speeds of Low and High but the only control over the heat is to use the Cool Shot feature. You have to be careful not to leave the air flowing against your hair in one spot for too long because the air is so hot. Also when removing the plastic concentrator nozzle, it's important for it to cool off first or to use a cloth to remove it. The nozzle gets very hot whereas the rest of the dryer does not.
The pluses for this hairdryer for me are the light weight, quiety motor, long cord, fast drying and the cool shot button.
The minuses are the extreme heat of the dryer, the nozzle getting too hot, and in the short run, the price. In the long run, the use of the dryer may justify the price.
Update On May 09, 2008: I believe you can find this hairdryer for a lesser price now. A friend of mine (who is a professional stylist) snagged one at a hairshow for $90! Also, the travel version is less expensive. And it has the benefit of the folding handle.
