Exactly what I was looking for
This was exactly what I was looking for. I live in a house with thin walls, and am a very light sleeper. Things like doors opening and closing would wake me up, and to compensate for that I would often keep a fan running. I wanted something that made a similar noise but didn't blow cold air across my room, and that's what this does. You can adjust the noise level, but it basically sounds like fan. Even on it's highest setting, it's not TOO loud, which is why they recommend you keep it close to where you sleep. If you do that, it's plenty loud enough to provide a consistent white noise that can distract you as you try to sleep. The device itself was deceivingly small; looking at my desk, it's about the size of a tissue box, but a little bit shorter. Still, this does exactly what I was hoping so I have no complaints.
