I guess a lot of the cost is in the re-engineering of the internal components and impeller…there’s a science behind it, selecting the right motor/impeller design.
I love the look. I don’t think it would sell for that price looking similar to the rest. Also, a cylindrical handle is perfect for the use since most people hold it in many different ways to reach different parts of their head, kind of like electric toothbrushes. Maybe it could be designed “more ergonomic” if it was for a professional hair dresser that is standing and drying someone’s hair able to walk around the person rather than twisting their wrist to reach different areas.
$400 is a lot but hey, if you use it everyday to make you look good I think people would spend it. Also if it works better and is less noisy then it would be a big plus. Heck if it is quieter I would buy it for my wife. I wonder if it’s a coincidence they released it a week before mothers day?
