LOVE this sound machine
I’ve bought four of these, one for each of my children. Back in 2021, I bought my first one when I had been using YouTube for rain sounds to soothe my baby. She ended up not being able to sleep all night without it, which made my power bill go up from running the tv all night. I searched sound machines on Amazon and came across this. The price was too good to pass up and the features mentioned were awesome so I gave it a try. It’s now 2024 and she still uses this same sound machine every single night. We have had no issues with it breaking or not working. I now have gotten then for all of my kids rooms age range from 11-newborn. They all love the various sounds but their favorite is the rain. There is white noise, music, rain, etc. The volume is great and can get very loud or quiet. It’s a great size, not bulky or big on any surface, great for traveling and doesn’t take up much space. You can use the cord in the wall or batteries which both work great. I would highly recommend this to anyone that has a newborn or anyone at all that needs a sound machine. It’s often on sale also, so I’ve caught it at an even better price a few times.

Rechargeable, for on the go
Love it, hubby was in the hospital it worked without take up a bunch of room. He was able to get better sleep quality even with the bed being to short.. it is bigger than expected, amazing features, noise level and volume control are great.. it does also work to drown out the thunder for the dog.. I love the design it is rechargeable and made for on the go..

Very soothing sounds and lots of options
Okay, the last "song" of the lullaby section (it's not really a song, it's more like chords) is amazing. I put it on for my 2yo in the evenings before bed while she has alone time in her crib reading books (she asks for this, her older sister is overstimulating) and so often I come back to find her just passed out! It's very soothing. The memory function is nice because I have the sleep timer set to 30 minutes so every time it's turned on, it's on the same song and sleep timer.

Love the sound options but wish it could charge or at least have an indicator light
I 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!

Updated Review
Update 1/10/24 - I wanted to be sure to update my review. When I last tried to used this white noise machine it worked perfectly. I was out of the country when I used it the first time around and I have to wonder if it wasn't a faulty outlet. I have since used this machine a few more times and I find it super convenient for traveling. I would recommend this product and buy it again, should I need to. PAST REVIEW ....With all the great reviews I chose this white noise machine for traveling. I always used my phone for white noise when traveling, but found it heats up, which made me nervous. The first night I used this machine it worked perfectly. I do wish it didn’t have a max time of 120 minutes, as when I’m home I run my other white noise machine all night long. That machine is also a radio/alarm and too cumbersome to travel with. The second night I went to turn this one and it didn’t work at all. I had it plugged in. I prefer to not worry about batteries when I’m away. Unfortunately I will be returning this product and trying a different brand. I do like that it’s compact and easy to travel with, though.

Not as advertised! Buyer beware!
I ordered this to take camping. It doesn't have the battery option. I contacted their customer service. They said, "This white noise machine you purchased is **designed to work only with a power cord**—no batteries are included in, and it doesn’t support battery power, so it can’t start with batteries." I said how can you say that when your advertisement plainly says you can use it with or without batteries? They said, "Regarding the power supply method of the product you consulted, we need to explain to you: this product has two versions, the “USB-powered version” and the “Rechargeable battery-powered version”. Currently, the product will be randomly selected from these two versions for delivery, and a specific version cannot be specified in advance. If you have a replacement request later, due to the randomness of the inventory versions, we cannot temporarily guarantee that the product we replace for you will definitely be the “Rechargeable battery-powered version”. BUYER BEWARE!!!

Works great!!!
I 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.

Isn't working plugged in, great with batteries.
The 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.
