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.

There is nothing I can tell any of you that the other reviews don't say. Instead, I'll offer my personal anecdote. 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... My safe, comfortable space was constantly being violated by noise pollution and there was literally nothing I could do about it. As bitter as I was, my upstairs neighbors weren't technically doing anything wrong, they were living their lives just like I am. 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 wasn'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 8AM 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. Please buy this. Please. Support this awesome product.

Favorite sound machine ever- we have 4 in the house. It is so effective has great volume versatility and my kids (and my husband and i) sleep so soundly with it. There is a 60 min timer option but we just always leave it on. There are many different white noise and fan sounds to choose from. We love it- highly recommend! It’s also very easy to travel with. We also love their wireless one!

We actually have two of these portable sound machines—one stays in our bedroom and the other is our travel one for the kids—and it’s been such a simple but essential part of our routine. I love how small and lightweight it is. It doesn’t take up space on a nightstand or in a diaper bag, but it still does a great job drowning out background noise and helping everyone settle faster. The sound is consistent and calming, and it’s become part of our sleep routine whether we’re at home or on the go. Having one dedicated for travel has been a game changer—no forgetting it, no unplugging at night, just grab and go. It’s perfect for hotels, naps in the stroller, or anywhere we need a familiar sleep cue for the kids. Simple, compact, and honestly one of those little things that makes a big difference in everyday life.

When I say that we have literally been using our TV , YouTube on a 24 hr white noise video EVERY DAY for 9 months ? I am not lying ( what we have to do for our kids ) I have worried out TV would give out any second . I decided to look into a white noise machine and came across this product and after reading the description , the features , I figured to try it out . Turned out so much better than I was expecting ! The volume is great and can be loud enough , it has different white noises / fan sounds and I love that it can stay on ALL NIGHT and not have the room get so hot because of a huge flat screen always on all day and all night . My son still falls asleep and stays asleep , great product . Recommend to other parents who need a white noise machine !

Easy to use, clear and smooth sounding sound maker. I use this both at night and when I’m trying to day sleep to prepare for my night shifts at work. Plugs in to the wall. Improves my overall sleep quality. For example, my son can come home and I don’t hear the noise of the front door opening or closing or him fixing himself a snack. Has a 60 minute setting and then auto shuts off, or a continuous setting. I prefer the continuous setting personally. If I accidentally do the 60 minute setting, I always wake up when it turns off. After you’ve chosen a sound, it remembers it the next time you turn it on. Has both white noises and fan sounds. I do wish it had some alternative sounds like rain and waves and frogs. But I’ve chosen a sound that works for me and tend to stick to that one. Have been using for about the last year and it’s going strong! It’s actually hard for me to sleep without it now.

This sound machine is AMAZING! I live on a busy street and have used a sound machine to block traffic noise for several years. The machine I had was OK, but when I recently visited my daughter out-of-town, she had this machine and I was so impressed with it that I decided to buy it (even though it's pricey!). It has a number of different sounds you can play, as well as volume levels, which make this perfect for our situation. HIGHLY RECOMMEND this product if you need a GREAT solution to your background noise problem!

Ordered because my husband starting working an 3rd shift job, so he needs to be able to sleep well during daytime. We use it every night, and I even use it when I sleep! I had heard about sound machines and I had researched a bit, and landed on this one. I love the sleek design and that it comes with a long cord. It is easy to figure out the buttons and even to use the buttons in the dark. The sound is good - we ONLY use the deep/low/brown noise. We don't like the other noises, when it gets higher pitches to white noise. It seems to be relaxing noise, AND blocks everything out so well!!! I was very surprised that I can keep sleeping through lots of noises that happen on the main level of the house, which makes me a happy person. Machine works so well, that I will be telling others about this exact machine too. Works good, we love that you can set it for a timer (but we use all night), and seems to very durable to us so far (we've used for a couple of months now). Can't beat the price for our happy sleep!!
