I received my Big Red Rooster White  Noise Sound Machine a few days ago. It is small and compact in size. I think the Big part comes in the sound it puts out. I know it aids in sleep but I also found it aids in stress relief. The ocean sound is completely relaxing. Most of the sounds are peaceful and relaxing. I wasn't crazy about the white noise one. I may be soothing to others, just not my taste. I would use this to help sleep also to unwind from the day. I really like and enjoy this product. [This review was collected as part of a promotion.]
