Adaptive Sound Technologies LectroFan High Fidelity White Noise Machine with 20 Unique Non-Looping Fan and White Noise Sounds and Sleep Timer

UPDATE 2014-FEB-14-- After owning the device a couple weeks, I had some realizations about why the Lectrofan is the best product. Other white noise machines often do not allow a very full range of pitch from high to low. The Dohm, for instance, does have a pleasing sound, but it is not capable of changing pitch too much, just muffling it really, changing the tone some too. Changing the pitch is the SMART way to block out particular sounds. If my roomie downstairs is listening to music from his cell phone or a higher pitched video game, turning the lectrofan on higher pitch blocks it out without having to blast the volume. If is he is blasting bass from his stereo, the lower pitches work better.The low rumbling of White Noise 1 (lowest Pitch) may have a pleasing sound (very much like "Brown Noise," a wonderful sound that many of you researching this topic have probably heard), but it will actually fail to mask many sounds that are higher pitch. Do not make the mistake of leaving it on the lowest pitch and just blasting the volume every time you need to block out louder noise. I suppose that white noise 4-6 would be the best general sound-blocking pitches for when you have a variety of noise in the environment. This kind of use is impossible with something like the Dohm, which I used for a long time before this. There are many sounds which the Dohm will never block without trying to use brute force with the volume (and it doesn't get anywhere near as loud as the lectrofan.) And the Lectrofan can be turned so loud that your room can sound like you are living under a waterfall or something-- so it can basically block out almost any environmental sound (though of course the reality will always be that you have to have it louder than the sound you are trying to block, which is the principle of all the sound conditioners. The point is that the sound is constant and you are not distracted by all the changes in noise.)-- I didn't think I would use the fan sounds too much- I just figured I wanted the white noise. The fan sounds are actually pretty nice. They are soothing and with no perceptible loop (lectrofan told me they were actually algorithms making the noise and not any recording of a fan.) The fans do have one issue that some people will enjoy and others will not, and most people may not even notice. They do have a repeating change in bass, which I notice more than others because I am neurotic about sounds. This change in bass will be more apparent if you have headphones on or earplugs in, but you might like it as a nice constancy. I doubled up on the lectrofans so I could get a richer sound in my room (which is very cool for white noise), but unfortunately the wobbly bass sound of the fans becomes even more distracting then. Others may enjoy this. The major downside of the fans is that they do not have the same range in pitch as the white noise, so they can not do the targeted kind of sound-masking I described above. I suspect people who are not very sensitive or neurotic (i.e., anal) about these kinds of issues will really enjoy the fans, though. I guess they are probably more realistic for having this trait.-- The white noise is pleasant. Higher pitches sound unpleasant at first, but give them a chance, maybe lower the volume. They end up sounding like fans, or rain, or a distant waterfall over time. I have the lectrofans in my room on white noise, but it still kind of sounds like the rushing of air or some other sound in nature with a similar pitch; the brain kind of fills in the gaps or hears what it wants from so general a sound. The sounds grow on you. Sometimes I will be sitting here hearing it as a waterfall, other times I will hear the same sound as air from an airconditioner or a huge downpour of rain. It is a really interesting phenomenon. Or maybe I am just crazy.-- The customer service was great. My first purchase would rattle when I turned the volume up to the highest levels. They sent me a replacement with two day shipping promptly with no questions asked. The new device gets VERY loud (way louder than the Marpac Dohm, it's main competitor) without losing quality.-- I owned a Dohm, but do not use it anymore. This device is more efficient, smaller, louder, and produces a better quality of sound and a wider range of sound. My Dohm started rattling after a few months and so I looked for a better product. Thank God this had been released recently.

I already had three different sleep sound machines but was intrigued by the LectroFan because of the many great reviews and also because it makes a variety of fan noises, something that none of the other three do. It would seem to me that the monotonous and constant droning of a fan would be a good way to not only drown out noise but help me go to sleep. My wife snores (which is good that I don't use my real name here) and I also thought that a fan noise would be more effective at masking the sound of snoring, than the other sounds that come on my other machines. I don't see how some of those other sounds help you sleep anyway - instead they would drive me crazy so I would only use the rainfall sounds.Anyway, I sent for the LectroFan, and I tried it out. And.. it was defective. I would get static on all of the different fan noise variations, and sometimes the sound would cut out intermittently, and sometimes it just stopped altogether. This seemed due to the power cord, because jiggling it affected the sound. I was going to return it but then noticed one of the few one-star reviews described the same problem I had. And I noticed someone from LectroFan urged them to call so they could take care of the problem.That's what I did - I called Lectrofan and am very pleased to say that the gentleman who answered the phone was very apologetic about my problem and right away offered to send me a new unit. Two days later a box arrived via USPS Priority Mail with a replacement unit, along with a prepaid postage label to return the defective unit. Now that's excellent service!I plugged in the replacement and it worked fine. I am very happy with this product. There's a good variety of fan noises (it also has white noise but I don't use it), it is really easy to operate, and it can get plenty loud - much louder than I need it to be, but at least it does have that capability. I also like how compact it is. My other sleep sound machines are much larger.I find the fan noise to be very effective and helpful as a sleep assistant. It does a good job of masking sounds - like snoring.What I am most pleased about is the excellent support I got when I called about having a defective unit. I am definitely happy I made this purchase. I was sort of skeptical about there being so many glowing reviews, especially when the first one didn't work right, but after having tried a proper one myself you can add me to the list of glowing reviews. It's a good product.

This sound machine is everything. I didn’t realize how much I needed it until I started using it nightly — now, I truly can’t sleep without it. This is my fourth purchase of this particular brand. I have one stationary next to my bed but also one that stays in my suitcase (I travel a lot for work). I've also given one to my daughter, who also can't live without it.The sound quality is rich and consistent, with no looping noise or weird electronic hums like cheaper models. I choose the "fan" option with a low sound. There are TONS of options to go with and you can adjust the volume up or down or even choose a timed setting.It’s compact and easy to pack, so it comes with me on every overnight trip — hotels, work trips, even family visits. It’s my little slice of calm in any unfamiliar space, and I never travel without it now.Easy to use, reliable, and makes such a difference in sleep quality. If you’re on the fence — trust me, this one’s worth it.
