I have only had my Bid Red Rooster Sound Machine for a short time, But I am in Heaven. There are so many big things in this little machine. It has 6 different sounds to help you relax with Rain,White Noise, Brook, Ocean, Summer Night and Thunder. These sounds are amazing. You can set the timer from 15-60 minute Intervals. This unit is so small and light- you can take it anywhere. Powered by AC Adapter or batteries. I have tried every sound and they are all beautiful and relaxing. You wont believe how easily you fall asleep. I am so happy with this wonderful little machine. [This review was collected as part of a promotion.]
