- Reviewed in the United States on June 3, 2025Bought at recommendation of moms on call and utilize for on the go or travel. Have two! Long lasting battery, good sound and easy to use. Don’t travel without one
- Reviewed in the United States on April 24, 2025Using it for a kids room. It has helped them sleep better and faster. We bought a second one the the other kid and now both want to use them every day.
- Reviewed in the United States on February 21, 2025Nice sound options. Small size great for travel. Looping of sounds is somewhat random with no breaks evident. Charges easily with USB-C provided. Other sound machines often have breaks in streaming sounds and/or constantly cyclical sounds which make them ineffective. This unit is a great option at a great price.
- Reviewed in the United States on January 15, 2025Tried several other brands of white noise machines that produced a rhythmic cycling of the sound that would wake me up. This brand is the first one that this cycling is not detectable at all. Very smooth sound that is constant. Just wish this particular model was a little louder, but it is still sufficient and works great.
- Reviewed in the United States on October 10, 2024We use it every night and every day during nap time. I highly recommend this white noise machine for regular use. We keep it plugged in all the time but if he goes away for a nap, it lasts for several hours without needing to take the charger along. Nice loud volume. Just don't place too close to crib or the decibels are too much for constant use for baby's hearing. Download a decible measurement app to test. I also figured out accidentally that it sings songs too even though it wasn't on the instructions. If you hold down the sound button and then push the power button at the same time, it sings songs. And you can flip between different songs using the sound button.
- Reviewed in the United States on August 14, 2024Sound is pretty weak and it’s convenient in that you charge it on the go but it should really be a bit louder. Compared to the full size plug in from the same company, this one is very weak. Charging seems to last a couple hours. Works if you’re in a pinch or really need it for a stroller walk/car ride but I would otherwise not choose to buy this.
If you’re thinking of using this for a vacation and will be staying at a hotel/airbnb, just get the full size version.

- Reviewed in the United States on February 6, 2024I have one of the standalone lectrofan units, which I absolutely love, but traveling with it felt precarious. I couldn't find a purpose-made case for it, and while it traveled fine, it felt wrong to keep shoving it in a bag without a care in the world.
This little guy has saved my butt. The selection of sounds is lovely, and the slim profile means it's easy to slip into any random pouch or pocket and then into a bag. Love that it's usb-c charged, because that's one less cord to worry about making sure I have. Puts out a great level of sound and keeps me sane when I'm sleeping in new/unfamiliar environments! When I'm not traveling, I actually keep it at my desk (work from home life amirite) for when I need neutral background noise.
Perfect little machine. Would not hesitate to buy again!
- Reviewed in the United States on January 2, 2025We didn’t carry this anywhere just used it at home in my sons room so we didn’t like bang it around or anything it still broke within a few months I was super disappointed

3.0 out of 5 stars Not quite loud enough
The volume didn't match the level we were expecting. We don't really use it much because of that. We use our phones instead.

5.0 out of 5 stars Good sounds, no loop, long battery life
Has been a life saver for my 4 month old's sleep. Long battery life so I can play it on car journeys or when we're out and about. Good volume levels and very relaxing sounds.
