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..

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.

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.

Designed to do what it is needed to do
This is a quality compact size, with volume adjustment for ease of use for sleep quality if you need white noise. It is slim line and easy to use. It was just as clear as my home machine and it was great for my sleep quality after testing out for one evening. I was purchasing for travel and realized that I just didn't need one more thing in my suitcase when I could put an app on my phone, This could be used in small spaces at home or a childs room when an app couldn't be used.

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!!!

Nice size and portable
Nice compact size, about 4" in diameter. Buttons are nicely arranged and nice size. Comes with a cord to hang it nearby. Charges quickly and seems to hold charge well. Nice selection of sounds and no looping. Good quality and good price.

Easy to use, good quality sound, plays a long time
This thing is great. Tons of sounds, responsive buttons, can get quite loud or quiet. If I had a baby, I would definitely use this to lull them to sleep. Yes you do have to scroll through every sound at first, but then it "saves" where you're at the next time you turn it on. At least, it did for me. I love the ocean, ambience, rain and fire sounds. Lots of variety and options.
