Customers find the sound machine effective at buffering outside noise and appreciate its portability, being small enough for travel and easy to keep in diaper bags. The device is simple to use with controls that are easy to manage, though some report it stops working after a few minutes. While some customers say it runs two whole nights without needing new batteries, others complain it goes through batteries quickly. The functionality and durability receive mixed reviews, with some units breaking within two months, and opinions on value for money are divided between those who find it good for the price and those who consider it worthless.

Same plug as my phone... I alternate them... charge the sound machine during the day and my phone at night.🌙
- Reviewed in the United States on March 23, 2025Color: BlackVerified PurchaseVery small but it works perfectly. Sound is very good. You have to search a little to find which sound you want it to play but after a while its probably easy since you know what you like the most. HAPPY HAPPY HAPPY
- Reviewed in the United States on May 22, 2024Color: BlackVerified PurchaseI like that this has several solid sound options. We found a music option that is really calming and my toddler loves it. We typically just go with white noise and I’ve found that not all white noise sounds the same (we had one machine that had only one awful option), but this one has multiple white noise options that are decent. My only complaint is I didn’t realize this doesn’t hold a charge. It either uses batteries (2 AA) or it needs to stay plugged in. It came with a USB cord and adaptor which was nice, but the adaptor broke after a month and I had no idea because there is no indicator light showing whether the device is using electricity or battery. I thought it was plugged in the whole time, and one day the sound machine just stopped working (turned into static). It took me a while to figure out that it had been using battery and the batteries had died. An indicator light would be so helpful!
- Reviewed in the United States on May 23, 2023Color: WhiteVerified PurchaseI really love this. It's an absolute life saver during travel. I travel for several weeks out of the year for work and hotels can be hit or miss in regards to noise. This has made my travel nights much easier. The sound isn't absolutely perfect, I would say it's close to how your phone speaker sounds. But I typically use the wave/white noise option so I don't even notice it. The speaker can get decently loud as well which is nice for the nights when you need it. It's also super easy to pack. Im terms of battery power, I typically use the 2-hr sleep timer setting, and with that, one battery charge lasted about 5 weeks of travel. It's really easy to pack as well. I debated more expensive versions of this type of product, but I'm glad I bought this version since it's a little less expensive and works perfectly for my needs. Absolutely love it and can't believe I've traveled for this long without it.
- Reviewed in the United States on September 12, 2022Color: BlackVerified PurchaseThe noise machine has a thin sleek design, doesn't take much space and came with a power cord and an approximately 6 inch string to tie. The sounds were fairly realistic and the speaker was great for both the white noise, fan sounds, water sounds and lullabies. Normally the lullabies or water sounds are terrible and indiscernible but that's not the case with this one. I like that you can turn off the light for night time and when the machine turns off via timer it fades out instead of abruptly turning off. It also has a memory function and turns back on to the same settings you had it on when it turned off.
However, this requires batteries or needs to be plugged in. Initially I didn't think that was a big deal until my batteries died while traveling and I was unable to replace them. I have tried two different (fully charged) battery packs and plugging directly into a wall outlet but the machine will not stay on. When it looses power this way it abruptly turns off. It wouldn't be as big of a deal to me if it at least worked with the wall outlet but it won't, which is disappointing to me since I'm using this as a traveling option and replacement for our at home white noise machines and didn't bring a pack of batteries thinking I didn't need them.
