It comes with 20 non-looping fan and white noise sounds.
Promising review: "This device saved. My. Life. Well, not literally, but it definitely saved my sanity. I'm a highly anxious person who is extremely noise sensitive and vulnerable to sensory overload. Cue moving into my first college apartment, where the upstairs neighbors' every footstep can be heard amplified and bass boosted through my ceiling. (Of course, before I signed the lease, the landlord didn't mention this... 'feature.') My room is right below their kitchen, so in addition to the stomping, I can hear all their yelling and banging around pots and pans all hours of the day and into the night. I was losing a LOT of sleep over this, and it ramped up my anxiety tenfold. I felt like I couldn't be at peace in my own home and dreaded having to come back here at all...
Anyway, I almost considered moving out or at least switching to an upstairs unit... that is, until I happened upon this amazing little device. I never cared for white noise machines that weren't true white noise; ocean waves and rainfall isn't as soothing when you have upstairs neighbors with lead for feet. You really need a good, loud, pure white noise that masks all frequencies and that your brain can easily ignore, so it seems as if there's no noise at all. This thing was absolutely perfect for me, as it only had white noise and fan sounds (and a variety of 'em!) that can get loud enough to mask anything. I mean ANYTHING. I can now peacefully snooze through not only my neighbors' stomping kitchen antics, but also the 8 a.m. garbage truck arriving bright and early every Wednesday. I don't wake up in the middle of the night anymore because my neighbor wants a midnight snack. I can come home after classes and enjoy an afternoon nap without disturbances. I sleep much more deeply and peacefully overall. And it's all thanks to the LectroFan.
I'm telling you, if you can relate to my situation in the slightest, just don't even worry about the cost. I would honestly pay double for this if I knew how much it would improve my quality of life." —Courtney
