I like this sound machine which is small , handy and very easy to use. It works great and help stay asleep throughout the night.This is perfect for adults and children to sleep better and sound. My favorite sounds are ocean, rain and white noise. I like that it has a timer you can play for the time you need it. I wish it's sound quality is little more louder as I need to put it near my head. Overall it is a nice product. [This review was collected as part of a promotion.]
