This noise machine is wonderfully compact and easy to use. It has six sound settings including thunder, rain, brook, ocean, summer night, and white noise. Each setting has its own button, so you can seamlessly switch between them. It also has a convenient timer that you can set to either 15, 30, or 60 minutes. This is awesome for napping or inducing a full night’s sleep for you or your baby. It also weighs very little and is super portable.
