This blow dryer burned out after about 6 months of very modest use - one person (me) with fine hair, using it about 4-5 days/week. One day when I turned it on, it made no sound but smoke came out - and that was that. It has a warranty but you have to pay to ship it BOTH ways to get a refurbished item, with no guarantee that the new one won't burn out too. This is way too expensive to have that kind of poor quality and inadequate warranty coverage. I would strongly recommend buying a different brand.
