FINALLY, I can sleep!
I'm one of those light sleepers who always used a fan to drown out background noise. I'm also one of those kinds who can "hear every little thing", which means fans rarely last more than a year (if that) before the motors start to whine, eventually leading to long nights of lots of whining and little sleep on my part. After perusing the "sleep fans", I was unimpressed by their overall performance. Nothing in stores today has a fan motor without some whine to it (which eventually becomes a howl and I don't need Banshees in my room at night, thanks), and living as close as I do to a freeway, well, let's just say I'm ready to start initiatives to ban motorcycles and after market "mufflers" for young, stupid wannabe racing enthusiasts. So, in desperation, I turned to sound machines. I tried the mechanical ones that use a fan to replicate the "white noise" of a fan. It whined. I mean, really? So it went back and I despaired of a cost-effective solution to my whine-inspired insomnia. Drinking had next day drawback, pills aren't my thing (and had even worse next day drawbacks, and both were more expensive in the long run), so eventually I came across this. I reviewed the video and although volumes weren't easy to ascertain, I decided that I'd give it a try. I haven't slept better in years. It took several nights to find my "sound", which isn't the machine's fault. I tried all of the "fan" noises, but sadly, my brain played tricks on me and I heard a whine from it (My wife didn't, it was all in my head), but since it was a whine that kept me awake, I opted for the white-noise sounds and within a week I found one I could live with. As it happened, I'm thriving with it now. I have it sitting on my headboard, about six inches from my head on the lowest volume and its surprisingly rich sound drowns out virtually everything short of gunfire (which, to be honest, isn't much of an issue where I live). Even the fans didn't mask the sound of the garbage trucks. But this does. It handles low-pitched or lesser volume, high pitched sounds as if they aren't there. Back-up warning sounds, it could do better, but the fan wouldn't have been better. Compared to a box fan (my previous go-to) it is absolutely outstanding. It's consistent, it doesn't have any repetitive or looped sounds, no breaks, and it does the job better than any fan I've ever owned. It's also amazingly small for what it does. My wife thought I had put a monster stereo speaker under the bed. If I want more volume, I can turn it up to "earthquake", which is to say the lowest volume is more than adequate for my needs. The controls are positioned a bit awkwardly if you want it on its side (which works better for me) and it's sometimes amusing to figure out which button does what in the dark, but it will remember both the volume and setting even if it comes unplugged. Best of all, it's tiny size makes for ease of portability, which means when I travel, I can have it with me to get a good night's sleep away from home, too. I've used fans for 35+ years. I'll never go back to them again. If anyone needs a use fan (cheap, you pay shipping), I can swing a deal for you. In the meantime, I'm catching up on sleep after a few decades of bad sleeping episodes. [ Update 06/05/2023: My little sound machine is trucking along without a hitch. There is NOTHING to change in the review, and this thing has saved my sanity, and possibly my marriage. I bought it in January of 2016, and 7 years later, it's going and going and going. If noise is an issue in your sleeping environment, this is far more reliable, and far longer lasting, than any fan or other mechanical sound-maker. There are few things in life that I gush about, but this is one of them, and I recommend it without hesitation or reservation. ]

THIS IS IT! Great to mask-out loud, random sounds or tinnitus
If there were a 6-Star rating I'd give it- and I'm going to be very granular in my review as people who need white noise to sleep usually know exactly what they need and are looking for- and what they are not: Some people just need a background/white noise to gently help them fall asleep. Others, like myself, have over-active hearing and minds that take forever to settle down at night - where any sound, big or small, can trigger us out of drifting off. I think I'm on the extreme high-end of this. I've done large box fans (can't take them with you everywhere and you wake up with cotton-mouth and dry eyes), and for the last 2 years I tried different apps on my phone (none were loud enough and all had pattern cycles your brain would pick up on fast enough that don't let your mind shut down. And, I found running an app on my phone all night posed other problems on running down the battery down even when plugged in all night (I did finally find a decent app but the sound coming off a phone it was still not natural enough somehow it was weird). My mother was a flight attendant. Why is that relevant? She flew pregnant with me until she was 7 mos - and so I heard alot of jet engines before I was born. My mom used to brag that she could vacuum under my crib and I wouldn't wake up (which is true), but that she never also understood why the slightest clink of a glass in the kitchen would wake me up in a panic. I've been this way as long as I can remember -- loud, droning sounds and machines with a contant sound or rhythm will put me to sleep in minutes. On a plane I'm out before take-off. But the slightest random sound wakes my brain up, as do irregular patterns of sounds. Anyone like me knows there is nothing more soothing than the sound of a loud dishwasher going in rhythm, or a furnace working away. I also have mild tinnitus - so it's also tricky to found a sound that will cover that up in your head to just the right degree. Anyone with me so far, has probably tried everything and you eventually just make-do with something that half-works, like my phone app did. Along with the LectroFan I also got the Marpac DOHM-DS Sound Machine (wrote a separate review on it- it was far too quiet for me and not the right type of sound, though a pleasant sound). I tried the Marpac first and disappointed by it, didn't have high hopes for the LectroFan. I turned it on, and it was like Christmas for Grown-Ups... 10 different types of fan sounds, and 10 different types of white-noise sounds varying in pitch. Seriously, this was like Christmas for the sleep-deprived who crave a solution for a full night's sleep. I ran through the different sounds back and forth, amazed at how they were all unique but similar variations on both fan types and white noise - 10 of each type! My only initial disappointment, which quickly faded, was that the volume was decent compared most things I've tried--- then I realized the volume was only mid-way.... For a guy who couldn't really find anything that was 'loud enough' to block out the other sounds - I found that on some of the fan/white noise variations I actually had to turn it down from full volume. Anyone who's gone through what I have my whole life trying to get to sleep and even sleep 3-4 hours at a time will understand when I say I almost got a bit emotional at the relief-potential I realized the LectroFan has. Honestly- the hard part will be trying the different fan/white noise sounds to find which I like best (having so choices, along, is mind-boggling). These are not fake, pre-recorded, twangy sounding- these sound like the real things. I am actually excited to go to bed tonight, instead of dreading wondering what sounds will bug me and get my brain going again, or how long it will take to try and sleep, how long I'll be able to stay asleep or how exhausted I may wake up. I'm trying "Duct Fan" tonight and I'll have to put it about 3 steps down from the loudest setting (which, again, is awesome that I found something that can go louder than I even needed). I should add, the low-end of the volume spectrum on this would be fine for babies, even. Size-wise, think about a stack of drink coasters. Not huge, not small - move something to another nightstand and make the room. It's also easily portable for travel. It's not pretty, it's not ugly. I am surprised they haven't gone the extra step of adding a clock/alarm to it, because it would be a great 2-in-1. I'm making a point to write this right after trying it out, because for anyone who's been as miserable as I have for so long, I'm hoping this helps them out, as well. I will most likely add updates after using it through the night a week or two, as well. Good night!

This machine has changed my sleep. After years of using earplugs to greater and lesser degrees of success, I finally decided to spring for a white-noise machine, so I Googled "best white-noise machine" and the LectroFan popped up. It's a bit pricey compared to some other options, but it is ABSOLUTELY worth the cost. There are about 8 fan sounds and another 8 white noises to choose from; you can run the sound continuously or put it on a timer to fade out slowly after an hour (a brilliant way to fall asleep, I might add - as the noise fades lower and lower, I find my mind is listening more and more closely to it so all distractions disappear and then I'm out like a light!). The volume is adjustable several degrees higher or lower and the machine itself is only slightly bigger than the palm of my hand. Lightweight, portable, I take it to hotels and when I'm visiting family and my sleep is consistently deep and restful. I put the machine on and I have an almost Pavlovian response to its soothing noise. This product isn't just for sleep; like all white-noise machines it can be used to mask unwanted sounds at any time and I've found it's particularly handy when I'm studying, working, or even meditating. A brilliant, brilliant little machine. 10/10.

Sonidos de baja frecuencia ventilador / white noise, al principio no parece funcionar pero con el tiempo se vuelve necesario, funciona muy bien

I live in an incredibly noisy area and am constantly struggling with my sleep. This machine is solidly build, offers a good range of sounds, is easy to use and very successfully blocks all kinds of noises. Dog barking, TV, people yelling, traffic, music - you name it - this fantastic machine will cover them all! This is the best noise machine I have ever used and I highly recommend it.

Fabulous, glorious peace... this little machine is stylish, compact and can belt out some decibels of soothing sounds to suit a variety of nuisance noise situations. It is costly, especially as I had to also by a Uk adaptor at £13.99, but so what for the price of masking the increasing amount and variety of nuisance noises around these days.

Es la mejor compra que he hecho si tienes el sueño ligero como yo te va ayudar mucho y si tienes que concentrarte para estudiar también estoy por pedir el segundo es lo máximo vivo en México y llegó en tiempo aunque llegó en un sobre no se dañó en lo más mínimo si venía abierta la caja pero me imagino que lo abrieron en la aduana quizás es cuestión de pedir un embalaje oculto para mayor protección
