This is absolutely wonderful first 2 night I slept so good. Has 6 different sounds.(rain, brook, thunder, white noise,ocean, and summer nights.) You can turn up or down volume to your liking. You can put it on a timer. Buttons are on top so easy to push instead of trying to look for them in the dark. You can either plug it or use 3 AA batteries. Small and compacted so it doesnt take up alot of space. [This review was collected as part of a promotion.]
