I love it. When we forced air dry Frodo, you can just watch the hair blow out onto the walls.
Noise really depends on the specific forced air dryers. I know a lot of people have their own, I go to a do it yourself dog wash. The dryer's there are not too loud. We tried a different dog wash and it was really, really loud. It was also a lot more powerful than the one we use now, but it was so powerful that we couldn't do Frodo's hips (he has hip dysplasia) because it hurt them
