HELPFUL TIPS… for the best sound machine.
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.

Incredible. Sounds EXACTLY like my box fan.
I was a little skeptical about buying this – first off, it’s a bit pricey. Secondly, a small device (about the size of your palm) that can make sounds like my box fan at home with that deep rumble that can cover up noise? I didn’t think it was possible – I was wrong. I sleep with a box fan on at home, but traveling with one is not really feasible. I tried all sorts of different noise machines, apps, etc, but they all had a shallow, high pitched sound. This thing sounds EXACTLY like my box fan at home. Very easy to travel with, and runs off USB (basically any USB charger will power it). It also gets LOUD, so on nights like last night when the crazy British kids next door were partying all night, I didn’t hear a peep.As I said before, it is a bit pricey, but sound sleep is worth every penny! HIGHLY recommend this – especially if you sleep with a box fan. You won’t be disappointed.UPDATE (12/2017): I’ve now owned the LectroFan almost 4 years now. It’s literally been all over the world several times. The fact it uses USB has been so convenient when traveling. I have a multi-usb plug that I use one world adapter to charge all my devices and it just makes it easy to not have to carry so much in my luggage. I even used this thing with my power brick when I went camping in the Grand Canyon! I will not leave home without it. The carrying case would be recommended where you won’t have cords tangling up in your backpack or luggage. (I also purchased the micro lectrofan about a year ago – it is pretty impressive for its size, but just can’t get near as loud as this original.)I can’t tell you how many of these things I’ve “sold” to people. Once they hear it, they’re amazed at how loud it can get. If you sleep with any kind of box fan, or if you have noisy neighbors or dogs – I HIGHLY recommend this device. Yes, it’s a little pricey but trust me, it’s worth it.UPDATE #2 (Jan. 2020): Well my Lectrofan has finally died. I think it shorted out in a hotel in NYC. Killed my iPhone cable as well. Ordered the newer/larger version – satisfied with it and is much louder, but the shape makes it difficult to pack in a side pocket of a backpack. (note that is for the NEWER version).

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.

India has become most noisy country whether urban or rural area , sale of this product is going to rocket high , purpose of blocking noise pollution is solved ,

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.

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.

Lo compré por recomendación y es un excelente producto, es posible subirle el volumen muy alto en caso de ser necesario y es muy práctico por que incluso lo puedo conectar a una batería (por usb) cuando se va la luz
