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.

Ours is going strong for 8 years! THE BEST PURCHASE I’ve ever made!
I bought this sound machine in February of 2018 and it’s STILL GOING STRONG! I loved it so much a came back and bought a second one two years later. This bad boy has been used DAILY and taken on dozens upon dozens of trips for almost 8 freaking years – and it’s not broken! You’d think the cord would’ve stopped working at some point but nope! Still using the original.I just had to come back and review this AMAZING sound machine so that others know what a great buy it is since it truly lasts! Which you can’t say for most things nowadays. So if you’re on the fence, I HIGHLY recommend this one!It’s the perfect size for travel, has a timer function, and the sound range is incredible. You can make it super quiet or really loud. Plus there are so many different types of white noise and fan sounds to choose from. Honestly this is probably my most used item I’ve ever purchased!(Don’t mind my dusty machine in my picture – like I said, it’s old haha)

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.

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!

I have been trying to find a white noise machine loud enough to drown out all noises, and finally the LectroFan device does that. Lots of options, a wide range of sound levels. I cannot recommend this enough if you are a light sleeper and need to drown out noises.

Excellent at blocking extraneous noise!!! The machine comes w/ European/UK/USA plugs. Shall travel with it. Haven’t slept w/ earlplugs since receiving it. Wish I had bought this years ago!

Me parece un gran invento. Antes no podía dormir bien por problemas con mis vecinos. Ahora no tengo que preocuparme de que hablen a voces. Muy útil.

Es un aparato pequeño, que cabe sin estorbar en el escritorio o mesa de noche, pero su bocina es potente.Se puede conectar con un cable USB a la computadora o a un cargador de celular.Genera varias frecuencias de ruido blanco y simula sonidos de ventiladores, que ayudan a dormir o a concentrarse en un ambiente ruidoso, debido a que están tapando lo que suena alrededor.El sonido que produce no es música relajante ni nada es eso, es algo como un motor de avión, monótono y denso. Se puede decir que es algo como un desodorizante que se usa en el baño, que probablemente no es un perfume bonito, pero es fuerte, no es desagradable y su función es ocultar olores más feos.Obviamente si hay una apisonadora trabajando al lado o un escándalo muy fuerte, el dispositivo no va a poder tapar el ruido de este tipo, pero es muy recomendable para personas que quieren eliminar ruidos más tenues, sin embargo molestos, como televisión, voces, vecinos, perros etc.

Can’t rate this highly enough. I don’t know how this little machine manages to do it, but it successfully masks the noise from the neighbour’s TV through the poor insulation in the wall. On the very rare occasion now when the TV manages to wake me, I find I don’t fully wake, but just notch up the volume on the machine slightly and drop back to sleep. It’s taken away the stress of the situation. If you’ve ever spent several nights a week awake at 2am when you have to go to work the next morning, you’ll know what I mean. It has multiple choices of white noise and fan noise, but I just picked one and haven’t had to change since. I really wish I’d bought it years ago.Update June 2017Still working amazingly well. Getting full night’s sleep every night. Can’t believe the noises I used to hear have completely stopped since I bought this machine – but I don’t hear them and I sleep well. I would recommend it without hesitation.
