I am really amazed at the sound this little machine puts out. I've only had it for two nights now but I love it! It is great at lulling me to sleep and masking outside noises. I live by a very busy street and have always used a ceiling fan, even in winter, for white noise so I could sleep but now I have this Big Red Rooster White Noise sound machine to help me sleep soundly. My favorite sounds are rain and thunder. This is so easy to use and I love the timer options. Thanks so much for this great little machine! [This review was collected as part of a promotion.]
