Query: Don't waste your money!

I've had the same problems as other reviewers of this product - after using it for a few weeks, the switch quit working so that the dryer must be unplugged to go off. Also: this device is VERY hot, even on the cool setting. My theory is that it dries hair faster just because it's hotter; not due to any magic ion benefit. It is also extremely loud. If you try to use it on a young child, you will probably either burn their skin or hurt their ears. This is NOT worth the money.
