Update: Had an Issue - Cust Svc Fixed it!
Update 2: Their customer service is amazing! I let them know about the issue and had a replacement the very next day. I guess that's because I happen to be in a one day shipping are for them. The replacement is working great and my baby is sleeping very calmly now! Update 1: Unfortunately, this unit stopped working within the first 2 months. Initially thought it was just a dead battery, but have tried charging on different cable and chargers with no resolution. When plugged in, the red light just stays on. The unit will not even power on when plugged in. Really disappointed. I'll be seeking a warranty replacement and will update accordingly. Original Review: LectroFan does not disappoint! I've become quite comfortable with some of the deeper fan noises from my LectroFan Micro (1st Gen). However after several years, the battery doesnt always hold a change the way it used to.. so I upgraded to the LectroFan Alpha and so far it's great. I love that they finally upgraded to USB Type-C, and love that they included a child friendly clip for use on a car seat or crib. My only complaint- despite being larger than the Micro, the Alpha is not as bass heavy, so if you prefer those lower tones, that's something to keep in mind. It's still great, but the Micro is just a bit deeper.

    Nice 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, 2025
    Tried 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.

    We 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.

    I 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!

    I love this noise cancelling machine! It has a variety of sounds and the volume can be easily adjusted. It’s rechargeable and can be stood up with the built-in easel on the back or hung from the loop on top. I sleep so much better with this little machine on and am so grateful for an improved sleep quality. It works consistently well and was worth every penny! I have tried other similar machines to help me sleep and this one far outperforms them.
