The Big Red Rooster White Noise Sound Machine has 6 different sound options: Rain, Brook, Thunder, White Noise, Ocean, and Summer Night. I didn't care so much for the Brook or White Noise effects: the Brook sounded to me like a bathtub running, and the White Noise sounded like TV static. Out of the 6 sound effects, my favorites were Thunder, and Summer Night (crickets chirping). The sound quality is crisp & clear, there is a volume control button, there's an option to set it to shut itself off in 15/30/60 minutes, it works with the included power cord or 3 AA batteries, and it's contemporary looking (the actual color is white, but it appears to be cream color in my photos). I also love the front facing speaker ... many sound machines have theirs on top, and the sound can't be directed. [This review was collected as part of a promotion.]
