Such a small machine with amazing sounds. I’m so happy with the white noise sound machine. I’ve been using it for a few days and have been able to relax and fall asleep. I work at night and this product was very easy to use. I just needed to attach the cord to the box and plug it in. I had several choices to choose from and was able to adjust the sound to the best choice for me to fall asleep or relax. There is a button that you could press to chose how long you’d like to have the sound machine on. There are three choices to choose from. I am very happy over all by the quality, the options available, and how it can adjust to my choice. [This review was collected as part of a promotion.]
