Nice concept but leaves something to be desired.  I was looking forward to receiving this sound machine particularly for the thunder sounds feature since I don't get to enjoy actual thunderstorms here in western WA. I was disappointed with the sound quality of both the rain and thunderstorm sounds as they seemed to have a lot of static. The sounds of the brook, ocean, and summer night sound are enjoyable though.  I do like that the unit is compact so great for traveling. I also like that I am able to set a timer for 15, 30, or 60 minutes. Overall it is an ok product and will suffice if you dont mind the static. [This review was collected as part of a promotion.]
