Its ok.

This thing works fine and has good features and sounds, it will make you relax and sleep.
Cons: Drains battery like a m@^#| er I have to keep my iphone on charge while using it, next day if I forget to close it from multitask bar it will drain 10% of battery in an hour. I have an iphone 4.
