Use it every night
Bought Sept 2021, reviewed May 2022 I did a lot of research before buying this as I wanted something I could travel with, (so USB charged) and also a specific sound of white noise that I had found on an app and played through my phone. I saw a useful You Tube review by an independent reviewer and he very helpfully played the sounds of each product, so I knew that this would replicate that exactly, whereas many of the others didn’t. It also has a good choice of white noise sounds, which are more what I require, as opposed to sounds of water/nature or melodies. It's incredibly compact and feels nicely weighty and well made. It is the perfect size to chuck in a travel bag and takes up next to no room on a bedside desk. Just about the only thing that could be improved is the buttons which are small and I find I can't usually operate without turning the light on. This could of course be because of my sausage fingers! That said, other than sliding the on/off switch at night and again in the morning, I tend to leave the volume and sound settings the same, so it's not really an issue. The sound it chucks out is amazing for its size and the directional speaker does make a difference - I always use it with this deployed. The first few weeks I had it I wasn't at home and didn't have access to a suitably close power supply, so I ran it off the battery and charged it during the day. I found it went 3 - 4 nights on a full charge. I like it quite loud, so maybe that uses more power than a quieter volume? Once I was back home I plugged in the USB cable and have it attached to that and the power source all the time and it sits by my bed. There's a small green light on the back, but it has never disturbed me and it could be covered with a tiny bit of tape if it was an issue. I recall reading reviews where people said the USB connection port was prone to failure, so I decided to leave the cable in to reduce wear and tear. I've not had any issues. In terms of effectiveness I find that it really helps me sleep and stay asleep. I live in 5th floor flat in a busy area, with a main road junction and the associated police/fire/ambulance noise that always accompanies their approach to it, day or night. There are rail lines and frequent aircraft noise from the landing and take-off patterns at LHR and LCY. I also have a selection of neighbours who don't always appreciate that night time is not the right time for loud noise and their gardens host the nocturnal gatherings of foxes. Anyone who knows what foxes sound like at night knows that it isn't soothing. There’s a primary school a couple of streets away and when the kids are out at breaktime the noise feels like they’re in the house with me. On top of that there is a public car park very close, so associated noise with that and the Police helicopters fly past at low altitude multiple times day and night, en route to from their base. All in all a challenging environment. Add to that that I really like my bedroom window open most of the year to provide fresh air and that I regularly have strange working hours which require sleeping at all times of day and night. So this thing has its work cut out. It doesn't blot out everything, obviously, but I find that I have a quite high tolerance for noise, so having it on quite loud does do a remarkably good job as it is a consistent sound, rather than all the random sounds of the outside. I woke up one morning recently and on turning it off heard a conversation going on below my open window, which was accompanied by a car engine running and the sounds of the car radio - none of which I had been able to hear with the white noise on. I know it would probably have woken my up pre-alarm had I not been using the Lectrofan. The door buzzer to my block is pretty loud in the flat and always used to wake me up. I unfortunately missed a delivery recently as this thing blotted out enough of the jarring ‘beep beep’ that I slept through a courier who arrived only three hours after I’d hit the sack. Coupled with blackout curtains, the Lectrofan makes me fall asleep much easier than I would without that buffer layer of white noise to smooth out the rough edges of the noise outside. It is very rare that I wake up in the middle of the night now for anything other than the call of nature!

Amazing little device!
Such an incredible little device. It’s way small than I thought (which is good!) and has so much sound power on Bluetooth or white noise setting. I’ve slept like an absolute dream since using it. There’s research I was reading about a continual sound being important and not looping which this is and it truly seems to have helped. Hopefully will be useful for baby too when she’s here!

Fantastic little speaker
We use this for white noise for a 2.5 year old and it's brilliant for that purpose. It's not easy for him to fiddle with the buttons, no cables for him to pull out, or little bits to make a chocking hazard. Plenty of choice with the noises and one charge lasts at least the full night, we've not tried it any longer. It's tiny so easy to hide on a window sill or somewhere similar and will be easy to take away with us on overnight trips. Since buying I have noticed the price fluctuating by about £15 depending on the seller. We bought it at the lower end and, although it's fantastic, I don't think it would be as good value at £50.

Great until it stopped working
This was great for using with our son, the white noise options were nice and we could choose one that sounded more like waves. However, after 6 months the device stopped working (while it can charge there is not output from the speaker). Low score because it didn't last long.

Brilliant 2 in 1 gadget
I really like this product. Before I was carting about a noise machine and a Bluetooth speaker and now I just need this. Now admittedly the speaker isn’t the same quality as the larger Bluetooth speaker, but it’s perfectly adequate for a hotel room. The sounds that are generated are good quality, the wave sounds are good but not perfect, sometimes they have a weird moment. But, for the convenience and size of the device I’m very happy. EDIT: having lived with this for a while, it has dropped a star. The noise it makes when you're connecting to bluetooth is so incredibly loud and shrill as to wake up anyone who is already snoozing. I have no idea why they went for this.

Really works!
I have used this at home for 3 weeks now and have to say it really works. I have always found it very hard to get off to sleep and then to not wake up with every noise during the night. I was very dubious about the idea of white noise and had tried it on my phone with limited success. I bought the travel one because it was cheaper and I didn't really believe it would work. But it does and I love how small and handy it is. Do I always get a great night? No. But every night has been decent which is unheard of in my 60 plus years of trying to sleep. I use the waves sound to help if I can't get off to sleep and it does also help keep me asleep. The white noise is good on nights when there is a lot of noise.

Powerful beast
Hunting for an airless fan for my ASD child who likes fan noise even in winter. This thing is tiny but mighty — loads of fan sounds and super portable. Only downside: the charge gives up sooner than I do

Great little gadget...
This little gadget is great, I've ordered my partner one too. Throughout the summer we've slept with tower fans and it has helped us sleep so well due to the white noise. Now it's getting colder and we don't use the fan, we're struggling to sleep, so I did a lot of research before settling on this one. Sound quality is very good and sounds exactly like the fan. We have slept so well since I bought it.

I use the device as a white noise sound machine for my child. It is of great help for any inside house noises and outside once of any type. Helps you relax and fall asleep quite faster.

As a devotee of the original Lectrofan, I was skeptical that this tiny puck would have the same oomph. If anything, it’s better than the original for several reasons. It’s not 100% perfect, but it’s pretty close. PROS: 1. Rechargeable, cordless for travel. Still works while plugged in, which I usually do at home. 2. Acts as a Bluetooth speaker. Easy to connect to your device. 3. Absolutely tiny, easy to pack. It’s about the size of a chicken egg. (I bought the recommended travel case and it’s great for packing along the charging cable, which you’ll need - see #2 below) 4. Decent sound. It’s not a replacement for a Bose system or anything, but for its size, it can fill a room with white noise or music/podcasts from your phone. 5. Has more than just 2 white noise sounds programmed onboard. I’ve got one basic favorite, but it’s nice to change it up every now and then. 6. The speaker is directional! Just gently twist the black part on top like you’re opening a jar, and it becomes a mini parabolic speaker. Helpful if you want to direct it at a door to drown out sounds inside a room, or just prefer the more direct sound. [I put my original Lectrofan in our guest room on a bookshelf next to the bed, and the shelf above changes the sound. With the directional speaker, the Mini stays true.) CONS: 1. When it’s plugged in, it’s got a tiny LED that glows red until it’s fully charged and then it turns green. The green is so bright that I will often find myself waking up and unplugging it in the night. Easily fixed by unplugging it, or slapping a tiny piece of electrical tape over the LED. 2. It’s only got about 40 hours of battery life, so you’ll have to be sure to charge it every 3-4 days depending on your habits. Luckily the charging cable is an easy one to replace if necessary, but not something you want to be without on day 4 of a trip. 3. So tiny you might lose it. Invest the $10 in a case, so at least you can find it in your luggage. OVERALL: Tiny powerhouse of a white noise machine & Bluetooth speaker. Small enough to take backpacking across Europe, but mighty enough to use as your primary sounds machine at home. I don’t have kids, but I can imagine how handy it would be for parents with a baby used to sleeping with white noise - great for long trips, car rides, play dates or family/friend visits with nap time, etc. Small enough to fit in a diaper bag, too. Highly recommended.

Una magnífica máquina de ruido blanco, pequeña, compacta y potente. Muy ligera y transportable, cabe en un bolsillo de pantalón. Se recarga por cable USB y la carga dura mucho (no sé exactamente cuántas horas pero no es necesario cargarla todos los días. Yo la utilizo durante toda la noche y también durante el día para las siestas de la niña). Por ponerle una pega, me gustaría que tuviese el sonido de la lluvia. Pero las variedades de ruido blanco que tiene son más que suficientes.
