This thing really IS good
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.

Most consistent and reliable.
This is the OG, the best white noise machine on the market. Why? Ours is going on 8 years strong. You have varying noise levels. It’s small enough to travel with. You can get low or high pitched noise (we prefer brown noise). It doesn’t skip. It’s doesn’t shut off randomly. Little kids can use it easily. It stays on the sound level and type you pick with no adjustments. Works every time. No cons.

Great sounds and easy to use
I have purchased so many of these devices, as I need a steady sound in order to stay asleep. (And hide my husband’s snoring.)I don’t want chimes, raindrops or rushing water or train whistles, I just want a steady whooshing noise. this one works great, it only has white (and other colors) type noise and fan sounds. It has a great volume control so it can be as loud or quiet as you want. If you prefer smooth fan sounds, this machine is just great. Plus the buttons are easy to use and make adjustments. Good price too.

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.

This item works for me even on low volume. Plenty of white noise and fan modes (10 of each) to find one that suits you. If you have a problem sleeping due to external noises, neighbours, traffic, wind, etc. and can’t take to ear plugs it is worth a try. Note the unit comes with the USA connector on the charging lead, it has to be removed by simply untwisting it before you can fit the UK adaptor, this isn’t explained with the instructions.

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

This is my second Electrofan of this model and the wiring is improved over the last one which I loved and which lasted 10 years when the wiring seemed delicate and broke away from the adapted when I gently tried to unplug it. The wiring on this seems more substantial. I love the product itself and use it every night, including when I travel. The sound can be increased in volume. This is a smallish attractive looking unit that is simple to use and is very effective in masking noise. I have used other products that were not as effective and with an over abundance of sounds that I did not feel necessary for my use. Great product and highly recommend it to those needing white noise to sleep, such as I do.
