Roundness makes a difference
I got this machine to help drown out the noise of very loud upstairs neighbors who stomp around all night like some kind of herd of nocturnal buffalo. Placing it in the hallway close to the wall, it creates the sense of a sort of diffuse ambient hum that i find a bit calming as my ceiling creaks under the weight of these nocturnal buffalos. Bottom line is, it's a lot better than those rectangular or disc shaped machines, where the sound is very superficial. This one has a depth to the sound that actually seems to work differently, and there are a ton of noise options to choose from.
