I like this machine a lot. I use it for my 3 month old. My favorite thing about it so far is the battery life. I’ve only charged it once and I’ve used it for about a week during her naps! There’s also a great variety of sounds it plays, which is nice. I’ve spent more money on one that just makes one sound in the past, so the different options are a great touch. It plays a sound that sounds like a crowded room of people talking which I loved when we left a busy restaurant and usually the sound disruption going from a loud place to outside wakes her, but I used that one and it was a seamless transition! Overall I’m very satisfied with this noise machine.
