Does everything it says and for the most part does it with no problems but anything involving white noise doesn't work properly on the machine even though it plays fine on the app on my phone. Starts off fine and then suddenly gets a loud mechanical BRRR noise like it's broken. Not helpful for sleep. Other sounds work fine– I tried recording white noise using the stories feature, which kind of works. Night light is good. Simple to use and great that it doesn't need batteries although placement is a little limited being plug in.
