This is advertised as "whisper quiet" but it is very far from that. When it's running it sound like there's a hamster powering this thing with a ton of tiny pebbles spinning around with him. Maybe it's considered whisper quiet if you're in the middle of a rock concert - that would likely drown out the noise. I emailed the company about the noise, they promptly responded asking for a video, I've sent them two videos of the noise and they stopped responding.
