This is a great little sound machine. It's small and sleek-looking, so it fits nicely on my nightstand. The volume controls have a nice range so you can keep the sounds pretty quiet or turn it up much louder. Though I have used all the sound options, my favorites have quickly become rain, thunder, and the ocean (and they are labeled which makes it even easier). As someone who has trouble sleeping, this has definitely helped me clear my mind at night and fall asleep faster. It's very relaxing! [This review was collected as part of a promotion.]
