This has saved me from sleep deprivation!
I have cat-induced insomnia. My cat meows besides the bedroom door until I wake up in the middle of the night. She gets enough food before bed and again in the morning, she’s been checked by the vet, she has plenty of toys, but still, she meows for attention. She isn’t allowed to sleep inside the room for other reasons (plus she would still meow at me even if she was inside). I’m not a person who can fall back asleep easily once completely awake. I start becoming anxious and thinking about things, and next thing you know, hours have gone by! It was getting to the point where I slept less than 5 hours a night most of the time. I thought I would go insane. I tried a lot of things before this sound machine. I wore high-quality, silicone earplugs. I left the fan on. I tried to put foam on the bottom of the door to block sound. Nothing was enough to muffle my cat’s meows enough for me to sleep through them! I didn’t have high hopes for this, even though I read through a lot of the good reviews before buying it. I always thought sound machines would only be as effective as a fan. When I tried this out, I first tried the fan setting because I liked how that one sounded. Then I tried the white noise setting and that one actually worked a lot better to muffle the cat noises. I think she’s even stopped meowing most nights now because I don’t respond to it anymore. The machine gets loud and I turn it up high. I still sleep with earplugs in, or else the sound would be too loud. The combination of the machine and earplugs are enough for me to sleep through disruptive noises, even as a light sleeper! If you’re worried about your alarm, if you keep it right next to your bed you should be fine. I tested alarms on my phone to see if I could still hear them loud enough, and I could! It might be an issue if you keep your alarm further away though. I haven’t experimented much with this machine because the setting I have it on with the white noise already works so well. You can adjust the volume to your liking. The sound travels up and helps to fill the whole space you’re in, rather than just occupying a single corner. The machine is also super small which I wasn’t expecting, and that’s great because it’s light, portable and not clunky. I worried where I was going to put it until it arrived and I saw how small it is!! Overall, if you suffer from noise-induced insomnia, or if you just need some comforting background noise to help you fall asleep, you need to try this little machine! If your cat is extra loud at night, then you especially need to give this a try. I’m so glad I found this!

My Wife Thought I Was Nuts..
For over a decade my wife and I have put on the sound of ocean waves on our beloved Squeezebox radio devices as white noise to fall asleep to. We had a pug that would snore pretty loud, so needed something to drown that out -- and besides that, when it's dead silent and the house is creaking or there's some other noise to fixate on, it can sometimes be hard to fall asleep. So the Squeezebox device worked well, except several times a year or more there were either power glitches or network glitches that caused the white noise to be interrupted -- which would inevitably wake us up and have one of us walking over half-asleep to reset the radio, sometimes cursing at it because it wouldn't just reset. I eventually decided that it'd be nice to have something that just did white noise and didn't require any network connection -- or would restart itself if the power went off. I now have 4x LectroFan white noise machines. Two of this model and two of their more basic model. They all work well. I have one in the guest room for when guests are over, we were using one by our puppy's crate for a number of months, there's this model in our bedroom for falling asleep to ocean waves and then a sister to that one that is only for traveling. My wife thought I was nuts for buying the first one. Probably because of the fact you can play white noise on your phone, we had the Squeezeboxes playing ocean waves, etc. But then after we used it for a while, she started to love it -- and also love the simplicity of them. You just hit a button. It remembers the volume and whatever tone you had previously set. If the power goes out, it comes right back on with the same tone and volume. And it just works! No fussing with loading an app, with a phone heating up or battery dying during the night, or network issues to interrupt the streaming of the white noise. So all-in-all, very happy to have purchased this and wouldn't hesitate to recommend. There is no looping. It can get pretty loud. And it just works! With these having an advertised power rating, I felt really comfortable buying it. I think it's under 3w or something like that -- and that's how it should be. Yes there are cheaper options, but do they have a noticeable loop in the sound? Do they consume very little power? Are they good build quality? Are they going to heat up or burn up or worse? I'd rather pay a bit more knowing I'm getting a quality product these days, especially if it's plugged in 24/7. This is a buy-it-once type of device that should last for years and years judging by other people's experience, so well worth the cost for something you'll use almost every single day IMO. Definitely recommended!

The best sound machine
The best sound machine! I have been on the hunt for a loud sound machine. This one is perfect. It has a variation of fan sounds. It drowns out all of the outside noise and I recommend it to everyone!

Range of sounds to suit all ears...
The small compact machine has a nice range of sounds to mask noises. I am giving it 4 stars because I wish it was easier to know which sound is which. They sound very similar, so I found it hard to distinguish between some of them and instead had to look at the list and count each time to try and find the exact noise I wanted--"brown noise and "pink noise"". Many sounds to choose from. I like how you can also control the volume and it is about the size of my palm. I got the white color machine. It has been helpful in masking noise from neighbors above me in an apartment building that play music all night long and I was hearing their base through my walls faintly but even more so with my head on the pillows. It has helped me get more sleep. It plugs into the wall or a USB. I have mine going all night long but it also has a timer function on it. Finally found a machine that works for me! Oh- and it also arrived SUPER FAST--another plus!!!

Many different sound options
Really nice noise that kind of fades into the background and helps you drift off to sleep. Many different sound settings and adjustments to pick what you like. Easy to use, just the push of a button.

If you're living in the Netherlands, this is a lifesaver! I wish I would have known how good this is before, it'd have saved me from years of misery. It drowns the noise of screaming children outside in the daytime, so you can focus working and shouting drunkards in the night, so you can sleep. I do need to put the volume quite high to drown the noise of the children as they're VERY loud, but then the sounds are almost completely muted. I like the compact size and white color too. Maybe would be nice to have more nature sounds. Though the basic fan sounds seem to work the best for canceling out noises. Such great machine, might get a second one at some point.
