We are so happy with the purchase of this little machine. Although we only ever use the white noise/static option, it has many more sounds available... Ranging from nature, water, womb, etc. it also plays lullabys which will be nice for our daughter when she's a little older. In addition to all of that it also has a pretty blue night light and a iPod connector - so when my daughter is much older it can be used as a speaker!! Bottom line - I love this little machine!
