I've had this for a couple of weeks now and find this noise machine to be relaxing. It's extremely easy to set up and to use. I actually haven't even read the instructions because the buttons speak for themselves. It's also very lightweight. 

My favorite setting is to leave it on 30 minutes playing ocean sounds. Even if I'm not going straight to sleep, just having that play in the background is super relaxing. One other thing I enjoy is the volume settings. You can adjust them perfectly to your own preference.

The only reason I didn't give this sound machine 5 stars is because I don't really enjoy all of the sounds much. And I also haven't been able to fall asleep from the sounds alone. I will say though that it is really relaxing. [This review was collected as part of a promotion.]
