I tried another kind of comfort-sound generator, based on speakers making electronically reproduced noses and white noise. I did not like it at all.I tried this one, and I was sold.It really does the job of providing comforting, soothing noise to block out other ambient noise and help sleeping. Fans and air movement are the only way to go.It has two adjustments that let you tune it extensively to your liking, by changing the size and orientation of the holes that the air comes through because of the fan.The body rotates. This appears to mostly tune the frequency, with a smaller effect on the volume. The top also rotates, and appears to mostly tune the volume with a small effect on frequency. With a little fiddling you can get it just like you prefer.It masks trash trucks in the street outside and wailing Burmese cats outside the bedroom door.Won't ever be without one of these again.

This is the best sound machine! It is exactly what we were looking for. I love that it is non-looping and it really provides a high-quality, reliable sound that keeps us asleep all night. We have used other sound machines but the one we used had stopped working, and we had been using a Bluetooth to play a white/pink/brown noise app from a phone, but it would cut out and wake us up, which defeats the whole purpose, so I was really excited to find this one. I liked how no-frills and simple it was. I had a different sound machine that was also a light, but it had so many buttons that you needed the manual to see what they were for and I hated using it. I ended up not even wanting the light feature either, so my mission was to find something simple and reliable, and mission accomplished with this device! I’ve sent the link to other family members as well. Something about the sound or the frequency or whatever it is about this machine really has provided us with a superior sleep than what we were experiencing before using this sound machine. It fits in the carry-ons we have so we are bringing it with us on a trip today as well. It won’t remember the sound setting once unplugged, but it’s so easy to use that it’s just a few presses of the button. I actually like that there isn’t a clock I have to reset or lights on it since I like to sleep in pretty complete darkness. I’ve had to dim or try to cover other sound machines in the past but I don’t have to worry about this one at all. I had been sleeping pretty terribly in the few weeks before using this sound machine, and I finally started getting a peaceful night’s sleep with this machine, so I am definitely recommending this if you like white/brown or fan noises for sleep (and if you’ve never tried them and struggle to fall or stay asleep, I recommend giving it a try! I struggled to stay/fall asleep my whole life until I started to sleep with a box fan to drown out the sound of a train when I lived in the city, but I get pretty cold at night so then I started using white/brown/pink noise variations and I’ve never looked back)!

This is the third one of these I have bought for me and the family. The sound is continuous and has many variations to suit your taste. It is small enough to take travelling - and that is when I need it the most. Have been using one of these every night for over 10 years and it has never missed a beat.

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 ,

We purchased this sound machine about three months ago. It has worked great. We live on a busy street and our bedroom is at the front of the house facing the street. We use to use an old CD player with a CD that would play with hours of fan noise. That started wearing out after years of use and were looking for another alternative. We bought this product and have been very happy with it. It has quite a few great options for sound and I think it has great volume control. You may find when first using it that you will have to reset the volume level at the beginning of each night. We did not about the first week or so. But now it stays at the volume level we set from the previous night. I would recommend this product. It may not be for everyone depending on your preferences etc.. But it works great for us.

We moved into a new home. I love the home.I love the neighbors. We saw the home was near a short side street and small shopping plaza when we looked at it. There was almost no activity on the street, as it was a Sunday when we viewed the home, and it seemed very quiet. No problem. The housing market was insane competitive at the time in our area. Overpriced houses, low inventory, multiple bidders, homes going under contract within 24 hours of being on the market, waiting for a miracle to get your offer accepted. Our offer was accepted. We bought the home. Fast forward to the first weekday I lived here. Turns out the short side street I thought was quiet is one of the the main throughways to the multitudes of neighborhoods around us. Think modified canned mufflers, wanna-be speed car sprint racers, booming bass players, garbage trucks, lawn maintenance trailers, public school buses, garbage trucks, city trolly system, motorcycles. Then to discover the loading dock across the way. Ugh. A. Major. Publix. Grocery. Store. Loading. Dock. Turns out their delivery trucks are huge. MONSTROUS. They have massive semi trucks, 18 wheeler trucks, refrigerator trucks...I have seen every kind of delivery/truck...dairy...beverages....produce...bread...chips...more breads...meats...more chips. Who knew it takes an 18 wheeler size truck delivery multiple times a week just to keep their potato chips isle stocked??! Surprise...IT DOES!! EVERY kind of delivery truck whizzing by our home, entering and exiting the dock and idling across the street at all hours day and night. It causes major noise, beeping as they back up, banging sounds when trucks let down or slam shut their loading ramps...not to mention vibrations in our walls and floors from the trucks. Then here comes the teenagers who get off work from Publix late at night booming the bass in their cars and letting it rip with their sawed off mufflers. So...we had crazy expensive triple pane laminated windows installed. This blocked out a lot of noise, but not all. Then we installed a fence around our home. I am very sensitive to traffic noise. I hate it. It feels like an intrusion in my home and it's unpredictable. The noise doesn't bother my husband, but then again he has some pre-existing hearing loss. I found the Lectrofan and am seriously thanking God because it works. I have 2 in our bedroom...(one near the window by the the outer wall and one on the interior other side of the room). I also bought one for the kitchen and one for the living room. I use fan noise #6 (attic fan) and it's very pleasant. I was told that it's a pink noise. I am not a noise color expert or anything...just in doing some investigating and my quest for peace I have heard that pink noise reduces anxiety and I increases memory...and that pink noise reduces the difference between the background hum and loud, jarring noises that jolt you out of sleep, like slamming doors, or a car horn honking. I keep the volume about halfway between the softest and loudest levels. The sound blocks the majority of the noise but blends into the background easily, so my brain acclimates and I forget about it. If I have to listen to noise, at least with this it can be on my terms. I recommend buying the Lectrofan. For high noise you may want to put 2 in the same room (placing one each on opposite sides of the room). It's well made, and small but effective...the white colored one blends easily with the lighter colors in our home. It's also compact so it fits easily in any area.

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

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.
