It's okay...Not great.
The nature sounds are not great quality. Unfortunately there are sea gulls in the background of the ocean waves sound...rather annoying as I just wanted the relaxing sounds of the ocean waves. Also the power light indicator is so bright, that you don't even need to choose one of the colored lights. Even with the light selected to the off position, it lights up...a lot. This would probably be fine for running during the day, but I don't recommend buying it for running in your bedroom at night.  I plan on returning this item & getting the AromaSoft one that I bought for my daughter to run in her room at night.  The only reason I got this one was because of the nature sounds.
