Our baby sleeps so much better with a sound machine playing white noise in the background, so we have one in every room she sleeps or naps out of convenience. We got this one for my parents' house and really like it. It's on the larger side and plug in only, so is best for keeping plugged in in one room, rather than for travel, but we knew that when ordering. It has a nice variety of sound options including several white/brown/pink type noises, as well as lullabies and other nature sounds. The volume options are great - I find that some other sound machines cap volume a little too low for my liking. And the white noise is very pleasant and isn't noticeably on a loop.
The night light option is nice, but not something we currently use. I do appreciate how easy it is to find the night light button (right in the center of the machine) in the dark. It would be great if the power button was also easy to find in the dark!
One little quirk is that the sound machine says something along the lines of "lickdesmells" in a female voice whenever we press the power off button. It doesn't bother us as we only turn the sound machine off once baby wakes up, so we find it to be a funny quirk, but if you prefer to turn the white noise off while baby is still sleeping, I could see this being disruptive. This could also be just my unit, I'm not sure...
So far, this sound machine has worked well for us and I would recommend it.
