Query: Good product

This blow dryer is a little on the heavy side, and the sound isn't exactly quiet either. BUT, like most people said, I do feel a difference in the way my hair looks and feels when I use this one compared to other regular dryers. My hair tends to be dry to begin with, so maybe that's why i notice the change. But if you already have smooth hair, I wouldn't know how the product performs. Another plus is that it dries my hair quickly...takes about 1/2 the time I usually need.
