it's fine I guess
I got this because I have very noisy roommates that I can hear through my air vent and I live right next to the alley so there are always people talking outside my window. It definitely helps with the roommate noise. However, I still have to sleep with earplugs in to drown out the noise of the white machine noise! The white noise is fine but it also makes an annoying mechanical sound in the background that might be some sort of fan. I find the noise to be really irritating, but I have very sensitive hearing. I would say that for the price, it was not worth the purchase.
